aka double penetration
No, no. I mean, double penetration was cool, but the guy couldn't do much about it itself, well played, gg. But I really like how he "covered" the doors with his crit build on range, then used C4 (clearly no idea where the enemies are) and rushed out like "I don't know what I'm doing".
Then just waiting for death inside, letting enemies go in, but w/e.
