Well Gears of war 2 has horde mode. And if you don't have XBOX Live (Gold) you can play multiplayer matches with bots =D. And don't worry about the sniper too much, it just takes more skill.
But if your up for a challenge i say L4D, but if you don't want to get bored of a game really fast i say gow2. ( I have both but i ALWAYS play gow2 when i play my Xbox )
Edit: lol i suck at quoting xD
