It took me about 40 (+) tries just to get through the opening sequence,and from there it got worse.It was the same thing over and over again, and just did not work for me. The game had a lot of potential, but the developers seemed (to me) to rush it and did not give it that extra little nudge. Which could of made it a great game to play, instead of a mild tempest in a teapot.
A terrible, terrible bug ridden mess. This game has a particularly annoying bug that prevents loading of the last 20% of the game. It seems to come up on about 1/4 of all users too. This was never patched and forced me to replay the whole game right from the start to complete it.
This was not the only bug I encountered. Numerous freezes, glitches in loading enemies so they never spawn... and this is just the technical issues.
As for actual quality, look up a review on a games website. The quality is something from an alpha build. It is incomplete in almost EVERY way. Terrible game.
