Although Garry's Mod is usually considered to be a full game, it has no game objective and players can use the game's set of tools for any purpose. Garry's Mod allows players to manipulate "props" – various objects that players can place in-game. Props can be selected from any installed Source engine game or from a community created collection. The game features two "guns" – Physics Gun and Tool Gun for manipulating objects. The Physics Gun allows objects to be picked up, adjusted and frozen in place.

Black Ops is a first-person shooter, retaining the same gameplay mechanics as previous Call of Duty titles. The player assumes the role of a foot soldier who can wield various firearms (only two of which can be carried at once), throw grenades and other explosives, and use other equipment as weapons. A player close enough to an enemy can kill with one knife blow. A character can take three stances: standing, crouching or prone. Each affects rate of movement, accuracy, and stealth.

Massacre meets machismo in this third-person co-op survival shooter. Repel demonic hordes with firearms, melee and hand-to-hand moves in various solo and multiplayer modes over eight open maps plus an Inferno boss stage. And for a change of pace, why not play as a trap-setting, minion-spawning demon yourself ?

In Magicka, up to four players take on a grand adventure to save their world from certain doom using a fully dynamic spell system. The adventure mode takes the players across three different levels, ranging from the lush forests of mountain valleys to the frozen halls of the Mountain King where wits and creative thinking are the keys to victory.

Guess what, this game has very little in common with the ones it wants to pass as a sequel of.
Chaos & Destruction is an arcadey racing game with minimalistic physics and where nitrous is not only used to overtake and ram opponents, it also heals your car. Tapping the additional invulnerability reserve will also prove useful to survive close encounters at 200 mph. The game features numerous vehicle classes, environments and game modes including silly "ragdoll olympics"-style challenges and 16-player MP.

Dead Space 2 is a survival horror third-person shooter. The player controls Isaac Clarke from a third-person point of view, looking over the character's right shoulder. The game features no HUD, relying on holograms projected from the player character and his weapons to show information such as messages and ammunition count, respectively. Player health and stasis are shown by visual indicators on Isaac's back. Isaac must fight an alien organism that infects and takes control of human corpses, turning them into "Necromorphs", mutating their bodies.
