I had a feeling that IGN would have this wiki complete by the time I got around to it, and it was complete and then some. Not only are there walkthroughs with screenshots, there are already videos of pretty much anything you would need.
As far as the walkthroughs go, the only complaint I have is their advice for the stealth portion in Act 2, Chapter 3. They simply just say to snipe the guards, but they give no recommendations on how to do this. The sniper rifle is too slow for the final gate, and the Lancer won’t reach as far as it needs to. I watched the video to see what it suggested, but the video has Marcus blowing the horn himself, which is a great idea for Arcade mode, but it’s not exactly smart for being stealthy. The video then continues to show how continue and survive with the alarm sounded. It’s very disappointing that no sound advice was given for this portion to be stealthy.
So why did I give this a 5/5? Well, I have to admit that the details of all of the unlockables and the Easter Eggs are what swayed me. Most of these, such as the Cluckshot and the Sawed Off Chicken Arcade game, were not in the BradyGames strategy guide. This most likely comes from the benefit of having a wiki that people can update constantly, as I know that these Easter Eggs were not present in the wiki when the game released. But hey, that’s part of the advantage of having documentation online–easy to edit and update.
All in all, IGN’s online guide for Gears of War 3 is on par with their guide for Portal 2. It’s great for what it does, in terms of video help and extras. I can’t wait to try to get some of these Easter Eggs, like the one for Dom crying. I made fun of him a lot in Gears 3, which I know is horribly mean, but I couldn’t help it.
