Ambush! It is the greatest. In battle 1 when I get the seeker powerup I wait behind a wall for "ehehehe" people like fire sword to attack me and in that moment I shoot 2 or 3 seekers into the hole or passage from which the enemy is coming. Then I hide as fast as possible to avoid enemy fire. I run away and find another good place for ambush. Hehe! Come and get me if you dare.

This works best with newbies!
