Now that the final version of Grimm has been released in it's 'mod' form for Doom 3 it's time for a complete walkthrough. This is the first of 6 walkthroughs that I will post the following weeks.
You will find all locations, secret routes, achievements and a lot of 'combat' tricks in these videos and they should help you hone your skills with Grimm.
