Left 4 Dead:
Left 4 Dead 2 is a brilliant zombie game that lends itself to excellent single player game play but even better coop play with friends. Also there are hundreds of free custom made maps available (see link below). I purchased the first game (Left 4 Dead) after one of these free weekends. I wasn't really into zombie games but decided to check it out when it was on its first free weekend back in 2009. I played all of the single player maps and then went online to play via the general community. At the end of the weekend i decided to purchase it because I'd had so much fun playing it. Every time you play it its slightly different. The swarms of un-dead that attack you always attack in different places each time you play which helps to extend the game play. When playing with friends or the general community you can set it so only your Steam friends can join a coop game or you can just join any online game. There are also several different modes so that you can vary the game play experience. All of which extend the life of the game. I've been playing L4D2 since it was released over 2 years ago and have hardly scratched the surface with respect to the custom content. There's also mods available that change the weapons and skins for the players.
The Game
Set in the zombie apocalypse, Left 4 Dead 2 (L4D2) is the highly anticipated sequel to the award-winning Left 4 Dead, the #1 co-op game of 2008.
This co-operative action horror FPS takes you and your friends through the cities, swamps and cemeteries of the Deep South, from Savannah to New Orleans across five expansive campaigns.
You'll play as one of four new survivors armed with a wide and devastating array of classic and upgraded weapons. In addition to firearms, you'll also get a chance to take out some aggression on infected with a variety of carnage-creating melee weapons, from chainsaws to axes and even the deadly frying pan.
You'll be putting these weapons to the test against (or playing as in Versus) three horrific and formidable new Special Infected. You'll also encounter five new “uncommon” common infected, including the terrifying Mudmen.
Helping to take L4D's frantic, action-packed game play to the next level is AI Director 2.0. This improved Director has the ability to procedurally change the weather you'll fight through and the pathways you'll take, in addition to tailoring the enemy population, effects, and sounds to match your performance. L4D2 promises a satisfying and uniquely challenging experience every time the game is played, custom-fitted to your style of play.

Rock of Ages:
A rock-solid combination of rock-rolling action, deep strategy, and captivating art and music from different ages of history, this is a game of crush or be crushed! Two castles stand opposed; one is yours, the other is your enemy’s. They're a jerk and their castle sucks, so you’re going to try to smash it using an enormous boulder. Even as they build up their defenses, you're ready to roll over them in order to raze that unsightly tower. But beware! There’s a giant boulder headed your way, too.
