Aganezer's review convinces me that at the very least the game is "good enough" and as I'm already interested in a zombie game that attempts to be more than a shooter, I think I'll like it. I'm interested in a few good solid hours of gaming and the price is right. I'll buy tonight.
Its a hard one to recommend right now due to the regular crashing. There are a couple things you can do to make sure you never lose progress.
1. When you finish a mission save immediately after returning to base. Once you return to base after a mission it will show a dialog listing everything you found on the mission. Click 'OK', then press 'ESC' to save. I've had some of the various fort screens crash. Its rare, but the last thing you want is to lose an entire completed mission.
2. Save right before you choose a mission. 99% of the crashes will happen when loading a mission. Like I said, its about 20% of the time. Don't let it catch you off guard and save before starting a mission.
There is no quick save during a mission, but I've only ever had it crash once during a mission so it shouldn't be a problem.
