During battle, tap on characters to mark the location for the player to shoot at, but bear in mind that the bullet takes a bit of time to reach there.
Switch between weapons when needed, and use automatic weapons when there is a swarm of enemies.
Do not forget to unlock support and powerful defense barricades; you cannot win certain matches without them.
