I downloaded both versions. The 2D version uses a tweaked version of the engine used by the mobile Predator game that came out awhile ago, the one set in South America, circa 2000AD. It plays fairly well and has some interesting stuff to it. The 3D one helps prove what kind of graphics you can do on a mobile, but unfortunately falls a bit flat. Some actions have sound affects while others don't, and combined with the sporadic background music, or lack there of, it makes the game sound disjointed and clunky, much like the game plays. The hit boxes a distances on melee attacks is atrocious, and the auto-targeting for ranged weapons sometimes finds things to target that aren't feasibly possible, let alone what I was trying to shoot. Also, movement is jerky and abrupt, and trying to pivot brings you to a complete stop, is rather sensitive, and doesn't let you move forward or back again for a bit. All in all, I like the 2D version better. It's probably because they were working with a constructed engine already, instead of building from the ground up with the 3D one. As a developer myself, I know this can be a chore, but seriously, don't release an incomplete game. Dirge of Cerberus does everything this engine is trying to do, and does it better, so I expected this game to be a least up to those standards.
