That's the game in a nutshell, but there's a lot more to it than that. Players band together in small groups, taking on waves of increasingly hardy enemies, unlocking better weapons as they go, and come the end try to take down a boss in an epic battle that, when balanced properly, just as often ends in defeat as it does victory. Apart from the inclusion of microtransactions for cosmetic items, this is an example of Early Access done right.Īll told Tripwire Interactive has built a near-perfect wave-based shooter, and there's a huge amount of detail hidden away in what on the face of it looks a very straightforward affair. It's been a steady evolution, with new maps and classes releasing over time, building on top of what was always a solid base. After an extended period of time spent in Early Access on Steam, the PC version of Killing Floor 2 is now emerging alongside the release of the game on PlayStation 4.
