The medium and large Rippers can burrow underground, sensing your presence on what they think is their land. If you don't see where one is coming, heh, you will hear it. The way this game is put together really is a nice change from the norm and although it does possess a story for any RPG fans out there you are going to be disappointed with this one simply because the story doesn't make a heck of a lot of sense. Though, I really wouldn't let that stop you from picking this game up. You've got to start over from the beginning.
Games automatically save at the beginning of each level.
Many people have been complaining of crashes, bugs and more bugs plaguing this great game. Oddly enough, I haven't had one crash, freeze or otherwise unwanted behaviour in the game thus far. I don't believe stability will be a problem in this game. However, if you want to keep up with it you're going to need a very beefy system. The recommended system is a PII-450 MHz, 128MB RAM, 16MB D3D video card and heh 1.3GB of HDD space.
