I played Gears 1 back in 2006 at a friends but until this week never played it again. Everyone on my friends list was playing Gears 3 and raving about it so I went out and bought all three (Gears 1 & 2 double pack was £15 used, sweet!)
Gears of War:
I spent most of the game feeling either scared stiff or like the biggest badass going! The firefights genuinely felt like you were pinned down at times and I died a fair bit due to my own stupidity! The audio adds massive amounts of tension when you're sneaking your way through bombed out buildings/factories and then suddenly something will jump through a window at you. Awesome! The story is pretty good but the game world obviously draws heavily from Aliens/Lord of the Rings/Warhammer 40k, which although obvious is also pretty cool, they seemed to have ripped off the best bits. Gun with a chainsaw bayonet anyone?! All in all, a great game and pretty ground-breaking at the time. Will definitely play through it again.
Gears of War 2:
I spent a lot more time feeling like a badass and a lot less time feeling like a little girl, so I enjoyed this one a lot more. Certainly some creepy bits but this one focused more on the firefights. Great bosses and interesting plot twists, awesome weapons and a really nice user interface built on the first game and made a great game truly excellent. I've not played online but I bet horde mode is fun as hell! I'll definitely be replaying this, especially if they do some more 25x XP weekends online.
Gears of War 3:
I've only played the first two chapters of campaign and I'm really impressed. New enemies, familiar weapons and controls, beautiful graphics and even more Lester Speight! I also played a bit online and enjoyed versus mode much more than Halo-style FPS games. I really hate the whole jumping-around circle-strafing thing now that there's an alternative. I'd have to say so far that it seems like they've taken the best bits of the first two, improved them and put them into this. Can't wait to play some more later on today!
