You wait ten years for a Left4Dead successor to come along, and then four swarm you from all sides within the space of a few months. We’ve already had the much-improved Vermintide II earlier this year, while Deep Rock Galactic’s Early Access adds a shade of space dwarf shenanigans to the structure defined by Valve’s co-op classic. There’s even GTFO lurking in the shadows of Q4, quietly hoping to be the Aliens game that Colonial Marines certainly wasn’t.

Right now though, there’s Earthfall, a high-intensity co-op shooter which switches out  shambling zombies for scuttling aliens. The game is set in the verdant forests of the Pacific Northwest, and sees players working together across ten missions of extraterrestrial-splattering action.
