I have finally finished the campaign and all I can say is, well done! The final battle is way more epic than the less than stellar boss battle in Gears of War 2 and much harder than Raam in Gears 1.
I love the new characters especially Sam. The dialogue that they scripted between her and Baird is awesomely funny. Plus she is sarcastic and I am afraid to admit it, but I am the same way. She just appealed to me. There are lots of loose ends that are tied up and a couple of sad moments but the story is engaging and I found myself not wanting to stop playing because I had to see what happened next.
Graphics are much improved. They paid more attention to the backgrounds this time too so the environments are richer and more detailed.
Multiplayer...well I have never been a fan but they have some modes to do like. Beast Mode is my favorite. You get to be the locusts and you have to kill all the humans within a certain time limit. Managed to get together with some friends and beat all 12 waves on Insane. I am pretty proud of that. Of course Horde Mode is always fun. I like Warzone. It's like Team Deathmatch but you only get one life. King of The Hill is another one I like. Wingman is only fun if you are with friends or someone that is talking. My wingman died right off the bat and left me to fend off the others by myself. Capture the Leader is basically getting to the enemy leader and holding them hostage until the timer counts down. Then you kill them and your team wins.
Of course Team Death Match is there and I am still not a huge fan. I'll try it again and see what happens. Execution is difficult. You have to kill with an execution and you get 1 life.
This version of Gears has something new, tons of weapon skins and I mean tons. They have everything from rainbows and lightning. The problem with it is, you have to buy them. If you're on Xbox Live and you want every single skin, it's going to cost you 3600 points. To put it in perspective, it's $50 for 4000 points. They also have a "season pass." It's 2400 points and will get you the first 4 DLC packs. Now Gears DLC is notoriously expensive and they have said buying the season pass will save you 33% in the long run.
All and all, this game did not disappoint me and I definitely think it is worth picking up especially if you played the other 2 and want to know how the story ends.
