Awesome there is no other way to describe this game. Being a Die Hard fan of the first I was a little nervous this game would not live up to its name, but it has in spades.
The campaign is longer and better in many ways, although may I point it if your an experienced gears player, if you want to appreciate the excellent experience even more play it on hardcore, you will appreciate it that bit more.
On multiplayer I did notice a couple of lag issues when I first started playing, but they are becoming more rare by the day. Apart from this small niggle which has nearly disappeared altogether now, the multiplayer mode is even better which is saying something.
Overall gears 1 is up there on my best games ever made shelf and I thought there was no way they could make the sequel any better, but they have I just hope they keep up the good work for the next one fingers crossed.
