Going through the left outer door on the 3rd floor causes 2 enemies to spawn from the nearby bullet time room. This is skipped by entering from the right. Breach charges are used to maintain the damage bonus for getting a kill, thus allowing for multi-kills in a single shot.

Enemies can be repeatedly spawned by the wall camera. High score on this map may not represent player skill.

Edit by Wavuvi: Set 'real time' value to match in-game time for leaderboard viewing.
