Before Counter-Strike won the Mod War (1996-2003), it was common for total conversions to take cues from John Woo films. Mods like Action Quake 2 (and its Action * derivatives), The Opera and The Specialists made multiplayer that wasn’t simply about running and shooting, but about doing both in style, preferably by diving sideways in slow motion through a skyscraper window while idly daydreaming about how good the Matrix sequels were surely going to be.
Those days may live again (even the Matrix bit, if you still dare to dream): some of the makers of the Specialists have released a free, standalone multiplayer shooter called Double Action: Boogaloo. Free as in free, that is; no microtransactions or free-to-play infrastructure, just a simple game of wielding pistols akimbo and releasing flocks of doves. There’s a new trailer and more detail below.
