An excellent sequel...
Pros:
Excellent add-ons were made to the game such as:
1. Matchmaking: Similar to Halo, the way they match you wtih players. When Gears 2 first game out it was ridiculously slow but now as days progress, matchmaking has really gotten faster. They do not have a number level system but an army rank system.
2. New Weapons: They added heavy weapons such as the chainguns, and mauler. Also added gas grenades which in my opinion arent that useful.
3. More executions: Allow you to do the basic curb stomp or a unique weapon dedicated execution with the punch of the y button when your opponent is downed.
4. New mode: Horde mode is a new mode in this game and is one of the best reasons to buy this game. I'am not that great online playing against other players so you verse a group of bots and there are 50 waves. The waves get more difficult as you go closer to 50.
5. Bots: Adding bots to games makes sure that you are never lonely in your multiplayer matches.
Cons:
1. Story was expanded but after more story expansions, they still left some major questions unanswered and even more questions arose.
2. Guest sign ins are a hastle. You are only allowed to do private matchmaking with your guest which requires you to invite friends or bots to play and whenever someone signs out you return to the main menu, leading to more load times.
Gears 2 is better and "more badass" than the first and i recommend this to all xbox 360 owners.
