Joint Attack and Defense: How an Alliance Turns Separate Fleets into a Unified Force

War for Galaxy is not the type of galaxy game where you can endlessly develop a planet alone and hope that your personal fleet will be enough for all situations. Here, space is alive: planets grow, fleets move, neighbors look for weaknesses, and major wars quickly reveal the difference between a solo empire and a player who knows how to act in formation. Therefore, War for Galaxy is perceived not just as another space game but as a full-fledged online strategy with territorial pressure, collective sorties, and real space combat game situations.

An Alliance in this system is not just a decorative signature next to a nickname. By game logic, it is a union of players creating a shared Alliance multi-account to capture and control territories in the galaxy. If a regular account is a player's personal empire, then the Alliance is a joint military and territorial structure. Through it, members can transfer resources and ships into the multi-account, participate in joint attacks, and fight for other alliances' planets.

That's why the strength of an Alliance consists not only of the number of ships of individual players. More importantly: how well participants can turn scattered fleets into a unified system. In good browser strategy games and online strategy games, what matters is not just production but discipline: who covers the frontline planet, who organizes the gathering, who doesn't arrive late at the target, and who prepares the infrastructure in advance.

In this guide, we will cover two key mechanics of collective combat. The first part is "Defense": how allied fleets temporarily become a shield over a player's planet. The second is "Joint Attack": how the Alliance gathers multiple fleets into one striking fist. Together, joint attack and defense in War for Galaxy turn the Alliance from a list of participants into a real fighting machine.

Part I. "Defense": How Allied Fleets Become a Planet's Shield

"Defense" in War for Galaxy is a specific fleet mission. It allows players of the same Alliance to temporarily place ships in orbit around an allied planet to strengthen its defense. If an ally at the frontline has an important colony, resource depot, or planet controlling a system, Defense enables turning it from a solo target into a common position for the Alliance.

Important limitation: this is the only way to defend each other together. You cannot simply transfer a combat fleet to another player or place ships arbitrarily on someone else's planet. The working scheme is one: choose the "Defense" mission and send the fleet to an ally's planet where the necessary infrastructure is prepared in advance.

Who Has Access to Defense

The "Defense" mission is available only between members of the same Alliance. You cannot cover a random neighbor, a temporary partner, or a player without a shared alliance composition. The mechanic is tied specifically to the Alliance structure: common front, common coordination, and common responsibility for key coordinates.

To send, select the "Defense" mission and specify the allied planet's coordinates. Antimatter is consumed once—only for the flight. Holding the fleet in orbit in Defense mode does not require additional fuel; thus, after arrival, ships can stand guard without constant antimatter consumption.

The Role of the Refueling Base

The main condition on the receiving side is that the defended planet must have a Refueling Base built. Without it, Defense is impossible even between allies. For active alliance wars, this infrastructure is essential: you can have strong allies, but without slots for their fleets, the planet will remain without collective cover.

The Refueling Base requires Alliance membership and costs 20,000 titanium and 40,000 silicon. It has no consumption, so after building, it does not burden the economy. Its function is to determine the maximum number of fleets that can be present on the planet in SAB mode—that is, in allied Defense mode.

The rule is simple: the Refueling Base level equals the number of slots for allied fleets. A level 1 base allows placing one allied fleet, level 3 allows three fleets. Therefore, for planets the Alliance intends to hold, the Refueling Base level must be planned in advance—not when an enemy fleet is already heading there.

Deployment Duration and Fleet Return

After arrival, the fleet automatically joins the planet's defense for 3 days (72 hours). This is not a transfer of ships or change of ownership: the fleet remains yours but temporarily stands guard in the ally's orbit.

After the term expires, ships return to their home planet. If the situation changes—the attack is canceled, the frontline shifts, or the fleet is urgently needed at home—Defense can be canceled at any time. In this case, ships will also return. However, fuel is not refunded: antimatter spent on the flight is not compensated upon cancellation. Therefore, before mass deploying fleets into Defense, check coordinates, free Refueling Base slots, and the actual value of the planet.

How Combat Works in Defense: Reports, Allied Fleets, and Risks

When an attack arrives at a planet with allied fleets in Defense mode, these ships are not mere bystanders. They fully participate in the defense alongside the planet owner's fleet and ground defenses. The attacker faces not just a single personal army but a collected Alliance shield.

At the same time, Defense does not make a planet invulnerable. It only adds allied fleets to the defense. If the attacker is stronger, has better composition, or penetrates armor and shields more effectively, defenders can still suffer losses.

Combat in War for Galaxy lasts until one side is destroyed or 10 minutes pass. If no winner emerges, the battle ends in a draw. Damage is absorbed by shields first, then armor. Destroyed defenses can recover regardless of battle outcome according to their recovery chance, while destroyed ships restore only upon victory and according to their type's recovery rate.

• All defenders participate in the fight. If several allied fleets are on the planet, each joins the defense during an attack.
• Battle reports are sent to all participants. Not only the planet owner but also players whose fleets were in Defense receive the report.
• There is a reconnaissance nuance. If the attacker is destroyed in the first round, they do not see the defending fleet's composition—only participants' names.

The most unpleasant trap is attacking a planet where your own fleet is in Defense mode. In that case, the fleet will fight against you. The game does not exempt "my ships": if assigned to defend an allied planet, the fleet fights on the defense side in battle.

For an active Alliance, discipline matters as much as fleet tonnage. Officers and coordinators find it useful to keep a simple record: who deployed a fleet, to which planet, when it arrived, and when the 72 hours end. In real-time strategy games, victory goes not to the one who remembers defense last minute but to the one who has key coordinates sealed with slots, fleets, and a clear return plan.

Part II. "Joint Attack": How to Assemble the Alliance's Unified Strike Fist

If Defense turns allied fleets into a shield, then Joint Attack does the opposite: it gathers the Alliance's ships into a single strike on the chosen target. This is not a magical damage bonus or a reward for simply being in an Alliance. Joint Attack is a mechanism allowing Alliance members to combine fleets into a single combat fist and deliver a coordinated strike.

Main point: this is the only way to massively unite fleets in an attack. In a regular attack, each flies and fights separately. In a joint attack, several fleets arrive synchronously at one target and participate in a single fight. Players value such space battles in strategy games, online strategy games, and spaceship games: it's important not just to have a fleet but to bring it to the target simultaneously with allies.

Who Starts the Assembly

The organizer launches the Joint Attack. When sending a fleet, they choose the "Joint Attack" mission, specify target planet coordinates, and set arrival time by speed settings. After launching, all Alliance members see a star icon next to active fleets—a signal that assembly is underway and others can join.

The organizer is not just the player who clicked first. They set the rhythm of the entire operation. If speed is chosen incorrectly, some allies physically won't arrive on time, resulting in an incomplete attack instead of a full strike.

Why the Organizer Must Be the Slowest

The key rule: the organizer must be the slowest participant. All other fleets need to arrive on or before the set time. If an ally flies longer than the organizer, they cannot join in time to arrive simultaneously.

Therefore, before the start, check the distance to the target, ship speeds, fleet composition, and antimatter consumption. This is especially important if heavy or slow ships participate. In spaceship games, such a "small detail" often decides a raid's outcome: one fleet arrived—attack broke defense; one arrived late—and the battle math changes.

How to Join and How Many Fleets Can Be Gathered

Any Alliance member can join a Joint Attack if their fleet can arrive on time or earlier and if free slots remain in the attack. Joining happens through the Alliance fleets window. After the battle, all Joint Attack participants receive the report, not just the organizer.

The maximum number of participants depends on the organizer's "Navigation" technology level:

max fleets in joint attack = ⌊Navigation Level / 5⌋ + 1

For example, Navigation level 6 allows 2 participants, level 15 allows 4. Thus, an organizer with well-developed Navigation is valuable even before launch: they open more slots for the group strike.

Joint Attack doesn't directly increase damage. It raises effectiveness by letting several fleets join one battle, share damage, and concentrate power without scattered clashes. For a serious Alliance, the basic principle is not to throw ships one by one but to assemble a strike so the enemy receives all damage at once.

What Happens to Fleets in a Joint Battle: Super-Units, Technologies, and Fair Contribution

When the joint attack reaches the target, the game does not simulate chaotic skirmishes of each player's individual squads. All ships of one type from participants merge into a common combat squad—a super-unit. Corvettes become the combined corvette super-unit, frigates the frigate super-unit, bombers the bomber super-unit, and so forth. This rule generally reflects War for Galaxy's combat logic: ships of the same type fight as a unit.

Technologies—weaponry, armor, and shields—are calculated not by the strongest player or organizer but as a weighted average, proportionate to the number of ships each participant contributed.

Simple example: if 100 weak corvettes from one player and 1 upgraded corvette from another participate, the strong one's bonuses will be barely visible in the combined squad. A single strong participant cannot "carry" hundreds of weak allies' ships on their tech. This system prevents technological freeloading and encourages equal contribution.

Practical takeaway: it benefits the Alliance not to develop just one "technology leader" but the general level of players actively participating in attacks. The more balanced the tech and composition, the more reliable the combined super-unit.

Don't focus only on raw combat power. It helps roughly estimate battle outcomes, but equal power does not guarantee equal results. Final outcome depends on how fleet penetrates armor, how much damage shields and hull absorb, firing distance, and hits in favorable sectors.

Therefore, building an armada of one ship type is a bad idea. A strong fleet isn't necessarily the most expensive; it's well-assembled. Bombers are effective against defenses, Galaxions matter against fleets with skills, and Colossus is truly powerful but expensive, slow, and vulnerable without proper support. In joint attacks, prior arrangements on mass contribution, coverage of ship classes, and compensation for weak spots are critical.

Alliance Tactics: When to Defend, When to Attack, and Why This Matters for Ranking

Defense and Joint Attack are two sides of the same alliance discipline. The first holds key planets, covers weak spots, and reduces solo strike risks. The second breaks targets too strong for a single player and enables participation in alliance wars not by scattered sorties but by full operations.

The practical logic: if a planet is important for the frontline, resources, logistics, or system control, it must be prepared for Defense—build the Refueling Base and know how many allied fleets it can accommodate. If a target is too strong for one player, don't waste fleets piecemeal: better assemble a Joint Attack and strike in one battle.

These mechanics also impact alliance combat rating. It is formed not as a sum of individual ranks but through Alliance combat activity as a single entity. Points are awarded only in scenarios with joint actions—via SAB or Collective (joint) attack.

• Alliance vs. solo scenarios in rating have a multiplier of ×0.5: for example, when an Alliance attacks a solo player with a column via Collective attack. Rating rules also acknowledge defense of solo players via SAB; practical planning must remember Defense's basic limit—it is usually only available between members of the same Alliance.
• Alliance vs. Alliance via Collective attack or SAB yields a ×2 multiplier. Both Alliances gain points if their fleet or defense inflicted damage.
• Multilateral battle among Alliances, with at least two fleets per side, also gives a ×2 multiplier.

Private duels within Alliances, fights inside one Alliance, and battles without SAB or Collective attack do not count. In other words, solo raids might help individual players but Collective scenarios create real value for alliance combat ranking.

The scoring formula is clear: enemy losses—destroyed ships and defenses—are converted into build resources, then the total resource value is divided by 1000 and multiplied by the multiplier. If fleet and defense worth 800,000 resources are destroyed between Alliances, the base 800 points turn into 1600 at ×2 multiplier.

There is also a territorial war aspect. An Alliance can own a system if its multi-account has at least one planet there. If multiple alliances hold planets in a system, the owner is who has more captured planets. If tied, the system belongs to no one—and such contested zones often become centers of space battles.
