StingingVelvet: Well, this is the same demo they showed the press over a year ago, so there is some hope that maybe some rough edges are ironed out. The health mechanic and weapons and stuff are certainly final though, no question.
I know but apparently it's already a tweaked version of this demo, with some added section, and based on it it would requires more than some edge smoothing, also if the demo is not representative of the final product what release it at all ?
Personally don't really buy the excuse of "it cost too much to create a new demo from scratch" it's FPS, I can understand that for a open world game or a RPG it might be hard/complicated to "extract" a portion of the game and make a demo with it, but here it's just a silly linear FPS, you don't have any stats/choices/whatever to carry over, you don't have to add invisible wall to add to prevent peoples from exploring the world, they could take any single portion of a level and copy and paste it into the demo.
