Eurogamer has posted a detailed look at the first act of Microsoft and Epic’s upcoming blockbuster, Gears of War 2. Environments, new weapons, the improved enemy AI, and the amount of variety in the first act are all touched on. They also got a look at the new Horde mode and how it will work. Horde mode will feature up to 50 waves of incoming enemies. Apparently, Cliff Bleszinski himself has only gotten to the 27th wave. Sounds like Horde mode will be an excellent way to work towards the 100,000 kills necessary for the Seriously 2.0 achievement.
