Online is horrible
It sucks. Everything is lag or delayed on purpose. Example, having to wait a half second to climb over/up barriers. If you tap the "A" button too fast you just jump off not over unlike the first gears.
WEAPONS....
Shotgun: Yup they destroyed the shot gun. It's a nerf gun. I understand what they were trying to do with how you use it but its worthless now. When you quick aim and shoot like you did in there first gears it doesn't shoot. A second later as your running away it goes off.
Torque bow: Have to use this weapon to see how bad it is in MP. Nothing like the first gears. If you shoot it, it might go off. You shoot it at someone and you know you missed them but somehow you killed them. Totally inaccurate un like the Bow in the first gears where you can hit an elbow on a sniper. Got to say the head shots are pretty cool though.
Chainsaw: You cant stop it. Its the new shotgun.
Grenades and Boom-shot: The radius of these weapons are much larger and cause instant death no more downing which kind of makes these BS weapons at some points.
Flamer: Not much leeway with its accuracy. You pretty much have to be right on target.
Sniper: I like what they did with it. If the MP wasn't laggy it would be a great improvement.
MULTIPLAYER
In general and easiest way to sum up the multi-player is that it plays and almost feels like a typical MP-FPS but you get shot 3 times not 1 time and you die. Match making turned into a flop if your one of those people that liked joining random rooms and playing with those people for a while. Now you have to party up or you will have to search for teammates after every match. Gears one MP was fun. You could actually be good with the power weapons if you tried. Gears 2 they just leveled the playing field for people that don't play that much. The online feels blan very little replay value after a while. I was let down. They just needed to fix what needed to be fixed but changing the the whole way gears MP was is how epic fixes problems.
