Alien Swarm is one of the games I always played back since 2011, and I still play it. It is really rare to see other pros playing. It is really fun but also extremely difficult and challenging to play on Brutal, let alone Brutal Onslaught. Brutal Onslaught is the hardest mode to even play on. Surprisingly, we did pretty good for Landing Bay.

Big shout out to the team. Yes, they friends of mine. Everyone on the team is at maxed level. (Level 27) But only me and another team member at Max Level with Maxed Promotion (Level 27, 6th Promotion, which also is equivalent to getting Level 27 x6 times.)
Big thanks to:
