Making it in Unreal: how aliens think in the Left 4 Dead-like Earthfall

We’re coming up on Left 4 Dead’s ten-year anniversary. It’s an occasion worth celebrating, but also a reminder that, well, both Left 4 Dead games are really getting on a bit. While their design is timeless and remains unbeaten in the genre, they suffer for the smaller FPS advances they’ve missed out on: the subwoofer-rattling boom of a grenade in Battlefront, or the simple existence of aim-down-sights in COD.

Earthfall is an unapologetic update; the Left 4 Dead 3 that Valve hasn’t yet managed to make. Sure, the zombies have been switched for aliens who look like the second cousins of the Demogorgon, but the formula remains unaltered - only bolstered by fortification mechanics and the benefits of a modern engine in the form of Unreal Engine 4.

Left 4 Dead is obviously one of the best co-op games on PC - but what are the others?

“For us it’s a huge deal to have the basic framework of a game engine already put together, so that our small dev team can concentrate on the parts that make our game different,” gameplay programmer Rick Saada tells us. “And not have to worry about all the basic code that’s going to be in common across different games.”

Earthfall Unreal Engine 4

Unreal Engine 4’s robust AI system made the job of developer Holospark a lot easier than it would have been otherwise. Earthfall needed to simulate alien behaviour but also that of your companions. As in Left 4 Dead, any of the four slots in your squad not taken up by human players are filled by AI, who you have to trust to back you up and stage rescues when necessary.
