Wow, it's like we aren't even thinking of the same system.
ZombiU was a horrid piece of shit that sold way more than it deserved. The graphics looked more like a Wii game than a PS3, let alone WiiU title. It was the buggiest, glitchiest, most unfinished PoS I've ever seen (well, aside from maybe Aliens CM) and felt more like a poorly done, early beta build than a title anywhere near ready for release. I tried to play through it 3 times, and EVERY time I ran into a bug making it impossible to progress, and naturally the autosave would kick in instantly to ensure I was screwed. Characters falling through the floor and dying (making essential story items unobtainable), being trapped in the safehouse with no way out, and running out of C4 all halted my progress. And online multiplayer should've been a give-in for this game, but of course it's restricted to local only. Not to mention that the whole game felt rather bland and, aside from the British motif, lacked any real character/substance or identity of it's own.
I just want to say this one more time just to stress it...... if you explore too much, it is possible to get stuck in a position with no C4 and no way to progress. They designed a game that doesn't have enough of an essential story item to get through. Never, in all my years as a developer, have I ever heard of such asinine, lazy, unprofessional bullshit before, and I really hope people lost their jobs over it (though it's Ubisoft so I doubt it, they've always been the shittiest big-name publisher/developer out there). That level of carelessness is unacceptable no matter what job you do.
Now don't get me wrong, as a proof of concept ZombiU was great, and if they hired a completely different team to do a sequel and actually FINISH the game it could be a great experience. I really did enjoy most of the ways the game utilized the gamepad, and it had some pretty great mechanics and ideas in terms of battling the zombies. But that doesn't mean jack shit when your game isn't finished and doesn't work.
The only thing that blows my mind more than the fact that the game was released in this state was the reviews I read. Ubisoft must've spent some serious dough to get these reviews as high as they were (not that a 77 on Metacritic is that high, but it's double what the game deserved). I guess the fact that it was the only original launch title that wasn't an overpriced 2D platformer or minigame compilation had something to do with it..... and even ZombiU looks half decent next to Tank! lol.
So yeah, that's my rant. No way is ZomiU worth $15. It's worth a $1 rental just to experience the rather innovative uses of the gamepad in a horror game, but not a penny more.
