Left 4 Dead is a multiplayer co-operative survival horror first-person shooter game from Valve Corporation. The game has been built using Valve's Source engine.

Left 4 Dead pits four human playable or AI controlled survivors of an apocalyptic pandemic against hordes of aggressive "Infected". The Survivors' goal is to help each other make it through various scenarios to safety. The Infected are controlled by an AI that dynamically balances difficulty and mood depending on the players' progress and situation. In an alternate game mode, human players can control up to four mutated Boss Infected with special abilities and cooperate to stop the Survivor players.

Left 4 Dead 2 is the sequel to Valve Corporation's award-winning Left 4 Dead. Like the original, Left 4 Dead 2 is set during the aftermath of an apocalyptic pandemic, and focuses on four survivors fighting against hordes of the infected. The survivors must fight their way through levels, interspersed with safehouses that act as checkpoints, with the goal of reaching a rescue vehicle at the campaign's finale. The gameplay is procedurally altered by an artificial intelligence engine dubbed the "Director" that monitors the players' performance and alters the scenario to provide a dynamic challenge for the players as they progress. Several new features will be introduced, such as new types of infected, melee weapons, and a story-arc that connects each of the game's five campaigns together.

The Elder Scrolls IV: Oblivion  (often referenced as Oblivion) is a cult single-player role-playing video game (RPG) developed by Bethesda Game Studios and published by Bethesda Softworks and the Take-Two Interactive subsidiary 2K Games. It is the fourth installment in The Elder Scrolls action fantasy video game series, following The Elder Scrolls III: Morrowind. Oblivion was released March 20, 2006.

Oblivion incorporates open-ended (or "sandbox") gameplay. The main quest can be postponed or ignored as the player explores the expansive game world, follows side-quests, interacts with NPCs, slays monsters, and develops their character. The player is free to go anywhere in the realm of Cyrodiil at any time while playing the game, even after completing the main quest. The game never ends, and the player may build up the character indefinitely.

It uses DirectX9 3D output with HDR or Bloom rendering capabilities.
