Assault Mode

Assault Mode is a cooperative game mode for aircraft, ground vehicles and helicopters where players fight against the AI. The main objective is to defend the base from several waves of enemies. Team can consist of up to 10 players. This game mode uses the damage and flight models, and other mechanics, from Arcade Battles (including rearming in flight). There is no limit for how many times players can spawn the same vehicle, so it is possible to bring only one.

Unlike in other modes, it is required to pay SL to spawn in the vehicle (0.8 x the vehicle's AB repair cost), instead of when the player's vehicle is destroyed. Rewards are given based on how long the player survives the mission. In addition, the player's first battle of the day gives a special reward depending on the mission length (how many waves have been defeated). The minimal required amount of points in a battle to get the full reward (RP and SL amount) is 1,500, everyone after reaching it will get the same amount of RP and SL. The best reward that is possible to get is a 300% SL or RP booster and a universal backup for any vehicle.

Levels in Assault Mode

Air Assault mode

Depending on the BR of the aircraft being used, there are five level in Air Assault battles:

The first level includes aircraft with a BR of between 1.0 and 2.3.
The second level includes aircraft with a BR of between 2.7 and 3.7.
The third level includes aircraft with a BR of between 4.0 and 5.0.
The fourth level includes aircraft with a BR of between 5.3 and 6.3.
The fifth level includes aircraft with a BR of 6.7+.

Players can still use aircraft with a battle rating lower than the indicated range. For example, it is possible to use propeller-driven fighters in the highest rank battles.

Ground Assault mode

Depending on the BR of the ground vehicle or helicopter being used, there are six ranks in Ground Assault battles:

The first level includes tanks with a BR of between 1.0 and 2.3.
The second level includes tanks with a BR of between 2.7 and 3.7.
The third level includes tanks with a BR of between 4.0 and 5.0.
The fourth level includes tanks with a BR of between 5.3 and 6.3.
The fifth level includes tanks with a BR between 6.7 and 8.0.
The sixth level includes tanks and helicopters with a BR of 8.3+.

Air Assault

Objective

Players use aircraft to defend the base at the centre of the map which is located under the spawn zone. The AI can use three unit types: bombers, attackers, and ground artillery units. The number of active players affects the amount of AI units which is being spawned by the game, for example when there are only five players then the game will spawn only half of the normal amount of planes.

The total amount of waves is 15. The remaining amount of waves to spawn for the mission is shown in the bottom-left corner to the right side of the other indicators. The next wave appears when all planes are either destroyed or the time counter between waves reaches 0 (it is reset every time a new wave appears). The time counter's start value decreases as the mission progresses, so waves of enemies will appear faster and at the end it is possible to fight two at the same time.

Waves

Waves can be composed of (B) bombers or (A) attackers and in some cases it is (R) random (there's a 50% chance of getting either bombers or attackers). Bombers spawn 20 kilometres away from the base position at 3,500 metres altitude and they fly in a straight line towards their target. Attackers also spawn 20 kilometres from the base but at much lower altitude - 1,500 metres. Just before reaching the base, they start to dive to drop their bombs, and they can still be intercepted during that action.

A table showing when and what type of units spawn during the mission:

Waves
Wave	1	2	3	4	5	6	7	8	9	10	11	12	13	14	15
Type	B	A	R	B	A	R	B	A	R	B	A	R	A	R	B

The number of spawned units can vary depending on battle level (1-5) and number of beaten waves, the more of them that are destroyed, the more enemies that spawn and their number will be increased up to 4 times per battle (it happens every 3-4 destroyed waves).

Artillery units

The artillery units use different mechanics to the bombers and attackers. Though they do not have the range to directly damage the main base, they instead regularly remove points from the base's health pool. This pool is shown in the bottom-left corner next to the artillery icon. The points decrease for as long as artillery units remain alive and the battle ends when the base's health reaches 0.

Spawn of artillery units is random and can happen from the second wave, but its chance for spawn gets higher every wave. Once they appear, they will not spawn again until the 8th wave, at which time the random chance to spawn is reset and they are able to spawn again.

Enemy types

Depending on level, the game spawns different units, the higher is the level of battle the harder they are to destroy.

Ground Assault

Objective

Players use ground vehicles and helicopters to defend the zone on the map centre from incoming waves of enemy tanks. Helicopters are allowed only in the top tier bracket (BR 8.3+).

The main objective is to not let the enemy units capture the area on the centre of map and slow them down as much as possible. If the AI units manage to enter the capture zone, it will start to flash and the team will start to lose tickets, the more AI that enter it, the more tickets the team loses. The enemy units slow down upon entering the zone, and their shooting accuracy is also lowered. After successfully defending the zone and destroying enemy waves your team regain a small amount of lost tickets. The battle is lost once the team's tickets reaches 0. The counter in the bottom-left corner shows the remaining amount of waves to beat (including current one).

Destroying enemy planes is optional but highly recommended, some of them are equipped with weapons that can destroy player's vehicle in a single attack. Sometimes a pickup can appear outside the zone, it can repair the tank and replenish its ammunition. The number of active players affects the amount of AI units which is being spawned by the game.

Waves

Waves can be composed of four unit types: light tanks, medium tanks, slightly better medium tanks, and heavy tanks. Every wave, two planes are also spawned which attack ground units and player controlled helicopters. In top tier assault battles, SPAA units can also appear, they will engage only flying units. Usually the game spawns one SPAA unit per player in a helicopter, their range is so large that they can reach players very soon after they leave the helipad. SPAA units spawn during the 2nd, 5th, 8th and 11th wave and it happens 20 seconds after the tanks start to appear. Spawn position of ground units is random, they always spawn from seven different predetermined directions.

Some enemy ground units can attack player controlled helicopters by using their roof mounted machine guns, such as the Russian tanks on Kursk map. The accuracy of the AI remains very high even when driving at full speed.

Note: It is a viable tactic to destroy track of the front most vehicles to make them stop, but keep in mind that they can repair damaged parts, including the engine and extinguish parts that are set on fire.

Waves

The amount of spawned units can vary depending of battle level (1-6) and amount of beaten waves, the more of them are destroyed the more of enemies are spawning and the game increases their number up to 4 times per battle (that happens every 3-4 destroyed waves).
