Gears Of War is an extremely good game and one of the best action game i've played so far.
This game was a bit hard for me to finish.I finished the game in casual difficulty and I recall moments where i found it difficult to win a fight,or revive my teammate,or reach a checkpoint on time.
The weapons are really well-designed.My favorite one was the chainsaw with which i could actually slash enemies into pieces and this generated a wonderful satisfaction.
The multiplayer part is highly addictive.I've played 3 hours without stopping and i didn't even realise it.Time passes really fast when playing Gears Of War Multiplayer.Co-op is really addictive too.However,not many people play gears of war online today.This is probably because of problems with signing in Games For Windows.You must have an American account to play actually.I created a second email in order to play,where i set my country to United States.Then i signed up to Games For Windows with this second email.
Anyways Gears Of War is worth buying.Really good game.
