Earthfall devs: "there’s nothing that really scratches that Left 4 Dead itch"

As with most series that emerge from Valve, we have long since given up on a third entry in Left 4 Dead’s lineage. But, thankfully, many other developers have not. Vermintide 2 and Deep Rock Galactic have already demonstrated a willingness to bend the formula into new forms. And now, Holospark - a Seattle-based studio founded by Activision, Bungie, and THQ alumni - are having a pop with Earthfall.

If you are looking for a melee-focused horde game then check out Vermintide 2.

Given the information nestled away in that opening paragraph, you should not be surprised to learn that Earthfall is a four-player co-op shooter in which you battle waves of (this time, alien-shaped) threats. But, as well as deploying your own futuristic arsenal in place of diplomacy, you will also be able to turn the alien menace’s technology against them and fortify your position with useful kit such as barricades and turrets.
