In this FPS, players control weapons being held by the games AI. You must do your best to eliminate the other enemies before they kill your host. Using the mouse keys to aim and various qwer combinations, players can guide projects to their targets, providing suppresive fire for the host to navigate the map and reach his location. The host will actively find upgrades and new weapons for the player to use on the go, so the less damage the host takes form enemy, the safer it will feel to search his surroundings.
A confidence meter will also be in use, which will increase dor decrease depending on your current skill level. For instance if you miss enemies frequently and the host suffers tons of damage in return, it will have less confidence in you as a straight up horde killer and will in turn take stealthier approaches to dealing with enemies and navigating the map. However if you mow down enemies with ease and the host takes minimal damage in doing so, it will feel more confident and engage enemies frequently, as well as openly search wide open spaces.
The host is invincible so it is encouraged to take various approaches to how you play the game, though if it takes a substantial amount of damage for long periods, it will ultimately lose faith in you as a weapon and the game will end. DO your best to keep your host alive.
