Controls

The player can switch weapons with the number 1 and number 2 keys.

Melee attacks do not exist.
The controls are the same as most FPS games, but if you're new to the game, be sure to check the skill keys in the settings window.

Victory Conditions

Battles are fought in waves.
A wave begins with an enemy spawning in one of the four regions,
enemies always travel to the player's location.
The wave ends when all enemies are defeated, and the next wave begins after a certain amount of time.

The player wins if they survive 30 waves.
Every 10 waves, a boss appears. Be prepared to battle bosses with powerful patterned attacks.

Resources

When capturing an enemy, the player gains a certain amount of experience. When maximizing experience, players gain skill points and recover a certain amount of HP.

In addition, at the beginning of each wave, a supply crate spawns in the sky.
Attacking and destroying supply crates will give you a large amount of skill points and ammo.

In the Skills window, you can enhance your player's stats or gain skills that are useful against enemies.
