Another Thursday means it's time for another changeover of co-op game Killing Floor 2 will be going free July 7.
Killing Floor 2 is a wave-based co-op shooter in which you and some teammates take on massive hordes of gibbering undead. Tripwire Interactive lavished attention on Killing Floor 2's weapon models and , and there's an argument to be made that it includes one of gaming's best-feeling shotguns – especially when you've activated 'zed time' with a well-placed headshot, slowing the action down to John Woo-style slow motion.
You can customise your characters with loadouts, perks, and accessories, and teamwork is essential for survival, especially once you've reached one of Killing Floor 2's boss stages.
You'll also be able to snag yourself a copy of the deck-building RPG game Ancient Enemy starting July 7, which features much less clean-up after a few rounds.
