Killing Floor 2 -
This week's weekly challenge is probably the most difficult and frustrating I've experienced since getting the game... 7 rounds on hard difficulty... where ONLY headshots do damage. That's not so bad in the regular waves, but it can be trouble on the boss waves, because headshots are difficult to get on certain bosses, especially King Fleshpound, because when he charges, he holds his (bulletproof invincible) arm-blender-thingies in front of his face. So, to get him back to being not-chargy you have to let him hit you. That can really hurt. A lot.
Fortunately, I was playing berserker, which means I can parry with my weapon, as long as I hit the parry button at the exact moment the attack would otherwise hit me. That reduces the damage I would have taken to a couple points, but still gets a charging enemy out of ragemode because he thinks he hit me for real.
At any rate, it took us FOUR TRIES (an hour and a goddamn half) to complete this weekly challenge, and all four times it gave us King Fleshpound as the boss. (By that third time I was begging and pleading for Hans Volter).
So, anyway, here's a 4 minute video of our final triumph.
