STRAFE

Zone 3-1. Small polygons of mice will run across the map and you need to kill 9 of them. They do not disappear and can be destroyed at any time before the end of the first level. When you kill exactly 9 pieces, you can safely leave the level (but I recommend saving in the cryochamber).

Then in 3-2 you must find a door that will lead you to a room where you will be greeted at the end by an enemy with a magic hat.

So now the secret, here you need to destroy all 5 pieces of cheese. I recommend that after you have destroyed a piece of cheese, you also destroy the remaining enemies and if you are prevented from destroying the cheese, then simply kill the enemies around you first. Of course, they will appear next to the cheese again, but they will all be in your field of vision, and not somewhere on the side or behind. As soon as you pass you will be given a couple of bonuses and a trophy.
