Found out the hard way I'm better off using the Brandon mask and not the one that gives you the drill. Was clearing seperate rooms, hallways, shit the entire stage itself all in one combo. A+'s all day. Only a few more trophies to go till plat.
This game it's something weird for me. Got it on the PSV but didn't really like it; like at all. But now that i've tried the PS4 version, somehow the game clicked in me and i'm loving it.
