if you play a game to discharge your rage: it is your pick...
Graphic engine: nice, well working but old fationed and pretty far behind modern game standards.... anyway, it can not be considered as a strong part of the game....
Gameplay: like i said before, it is kinda repetitive and boring: it is always the same: go there, do that, opening your way through endless crowds of zombies... which become more and more dense, along gameplay. in addition, I think that in some cases it is unnecessary hard... a purpose of a game is fun, and not to enrage the player... I guess I can mention something that gave me a lot of fun for a while is a possibility to make incredible, sometimes completely senseless combinations of objects, in order to create funny and deadly weapons... many times does not make any sense: like wheelchair and car battery... wtf? of flashlight and gems... but it is funny, at least
Storyline: Silly and primitive, like a cheap 80's zombie movie. nothing new, nothing original
Controls: not bad, but can not be customized... no comments.
Overall: the game looks fun, at first sight, but it lacks good storyline, it is boring, and sometimes damn hard... but if you look for a senseless slaugther from the beginning till the end, it is a good choice.
