ICE: Keep in mind that weapons you pick up will use ammo, if you run out you cannot shoot!
ICE: Further in the room you'll see an enemy fairy guard, if they spot you they will chase and shoot you!
ICE: They are prettu dumb though and if you outrun them they'll forget about you.
ICE: Now shoot that guard to proceed.
