I n rare quiet moments playing Marathon, you may find yourself overcome by the iridiscently pretty planet Tau Ceti IV. This fictional world seems to radiate a chemical glow: powdery pink skies and lurid green vegetation fill the screen alongside supermassive architecture emblazoned with ultra-stylish, neon graphic design. Yet enjoy the scenery for a split second too long and you might catch a bullet, causing your character to bleed an icky blue substance. In such moments, the camera locks - meaning you must stare down at their unceremonious expiry. Marathon's considerable beauty is matched only by its clinical brutality.

The extraction-shooter genre is getting a little more crowded and a lot more stylish with the announcement of Mycopunk, a four-player, first-person romp from indie studio Pigeons at Play and publisher Devolver Digital. Mycopunk is coming to Steam in early access this year. Mycopunk stars four eccentric robots who've been hired by an intergalactic megacorporation to exterminate an invasive, violent fungus that's taken root on a valuable planet. Each robot has a specific class and moveset, but players can use any weapon or loadout with any character -- and that's a huge benefit, because there are a ton of wacky guns, upgrades and ammo options in this game. For example, there are bouncing shotgun pellets, bullets that hover in place and then dive down when you press the trigger again, and a rocket launcher move that also makes you fly.
