Bottom line, while the art may have seen a drastic change the gameplay largely remains the same. The simplicity in controls allows for focus to remain on one's opponent. That simple style keeps things fun. The stages are constructed well enough that you never feel cheated by the environment, helping to zoom in even more on player vs. player combat.
Killing Floor: Incursion is a pretty solid VR experience. The single player (or co-op) provides a great atmosphere. When it comes to getting the horror aspect to be actually horrific, Tripwire Interactive has done an excellent job. It's really that experience that sells it.
