Gears of War 2
I loved the first Gears of War, although not my usual kind of game I buy and plan, I liked how the story was progressing, and the combat situations. Even though linear, it is fun. Gears of War 2 expands and leaves off from Gears of War 1. The lightmass bomb from the first one didn't destroy the locusts, it just pissed them off more.
One thing I liked about the new one is that there is clippings and articles, explaining the origin of the locusts. In the first one, I thought maybe they were an invading alien race, or possible COG was invading their planet. But turns out they are actually genetic experiments gone wrong at a COG facility, possibly to create a master race.
In this one I found I run out of ammo more, so I got use to using the chainsaw whenever I could, and despite keeping an eye out for clippings, I have missed a lot of them which I plan to go back and get. There are some really fun weapons such as the flamethrower which is great against weavers. A lot more reaver attacks too.
The game seemed more focused on vehicle combat near the end, first on the bastile or whatever its called, and the reaver fights, and the awesome gun tank.
I can't help but think if the real army chainsaw guns and badass gears for you to wear, more people would join up. Killing the worm was an enjoyable storyline, when I was watching my friend John doing it, I remember saying "wait don't worms have multiple hearts", at which point after destroying the first, a second one working twice as hard could be heard.
The ending left it open again like in GoW, so I guess I have a few years before GoW3, but I look forward to it.
