Producer Tanya Jesson told OXM magazine that the early gameplay was "completely different than it is now," revealing the game had transformed from "a third-person shooter to a cover-based first-person shooter to a non-cover-based first-person shooter."
"We actually went through lots of iterations of how cover could work really well in a first-person shooter," Jessen explained. "But when it came down to it, once we started to see how great some of the weapons were coming along, we felt the core of Bulletstorm is the face of the enemy and the player figuring out what to do. So in that case, cover-based combat didn't really work so well."
Absolutely nothing to do with Epic's third-person shooter franchise then? What's it called? Gears Of Something.
