Improvements: -Opening doors when you can saves recoil frames, and there's quite a lot in this level, plus it allows to 1-shot some groups of enemies, further reducing the amount of times you shoot -You can ignore one knife guy that will get sniped anyways

To open the doors like this I use my right thumb on the D-pad, so I end up switching hand position all the time, which is not that easy, but way easier than doing it all with the left stick.

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