I just finished the campaign and Wow. It's freaking awesome and a really good ending. I agree the game gets better and better each chapter. I was a little underwhelmed by the first chapter, but it picks up fast by the second and there on out it's amazing. I can't wait to play the campaign again with 4 friends on Insane.
Horde Mode 2.0 is a freaking blast to play. I only got to level 17 with some random people. looking forward to playing this with some friends and going to wave 50. BTW the Boss waves are insane.
Beast mode is great. I only unlocked to about the third stage of locust so I didn't get to try them all out. Definitely a change of pace from everything else. It pretty disappointing there is only 12 waves and only takes about 12-17 minutes to finish.
The multiplayer is so polished and well balance. There is nothing bad I can say about it at this time. No lag or gliches I've spotted so far and it runs like a dream on dedicated serves. I'm going to be addicted for months.
Pros: Awesome story, Horde 2.0 is so much fun, Beast Mode, multiplayer is very polished, tightest gameplay and controls yet for a Gears game, amazing graphic.
cons: Beast mode should been longer, paying real money for weapon skins is lame.
Final Score: 9.5
