They might want to think about changing where the Reds spawn in Corridor, cause its a bunch of bull when you kill them on that ledge, then they respawn in about the same place or farther up ahead.
TO ALL NEWCOMERS: It is extremely beneficial if you upgrade health. Health > Defense, at least in the early game. After two health, you might want to upgrade once in strength or accuracy, just enough to get an uzi type weapon. These have plenty firepower if used properly, and you will last a awhile with your health.
