Splash Damage's Dirty Bomb (formerly Extraction, and then back to Dirty Bomb again) is stress testing its servers, and have shared a video showcasing best gameplay practices.
You can check out the video below, which offers a good look at the upcoming Team Fortress-esque free-to-play title from the studio behind Brink and Batman: Arkham Origins multiplayer mode. There is a stress on the beta test happening this weekend until Feebruary 23, and another planned for March 6. If you want to play, head to Dirty Bomb's website to sign up.
Dirty Bomb takes place in an abandoned London, following an ambiguous radiological attack. You are a mercenary soldier tasked with extracting important information left behind in the city.
