Havent went through the whole beta, but i think leveling was sped up. I picked it up and felt it was generic, but a couple minutes in and im hooked. I cant really explain why, maybe because it feels like halo so much? I personally cant wait to get the full game. I was wondering if there was chat speech in-games as well. They should add a classifields like form halo 3 since theres no matchmaking.
