Players take the role of Chell in the single-player campaign, as one of two robots - Atlas and P-Body - in the cooperative campaign, or as a simplistic humanoid icon in community-developed puzzles. These four characters can explore and interact with the environment. Characters can withstand limited damage but will die after sustained injury. There is no penalty for falling onto a solid surface, but falling into bottomless pits or toxic pools kills the player character immediately. When Chell dies in the single-player game, the game restarts from a recent checkpoint; in the cooperative game, the robot respawns shortly afterwards without restarting the puzzle. The goal of both campaigns is to explore the Aperture Science Laboratory - a complicated, malleable mechanized maze.

Developed by Trendy Entertainment, Dungeon Defenders throws action-RPG and tower defense gameplay into the proverbial blender to create a seamless mix of leveling, looting and high-action territorial combat for casual and core players alike. Dungeon Defenders features a lovingly-rendered watercolor art style and allows up to 4 players, online or locally, to take one of four distinct classes into fierce battle against ever-increasing waves of baddies and bosses across 15 arenas and multiple modes.

A variant of a tower defense game; the player as the War Mage must defend one or more Rifts on each level from an onslaught of orcs and other creatures that emerge from one or more entrances and traverse the level. Generally, each orc that reaches a Rift deducts a point from the starting Rift Score while specialized orcs may take off more points; if the Rift Score drops to zero, the level is lost and the player will have to start again. The orc armies arrive in increasingly more difficult waves, with each level having between four to twelve waves. In general, waves will begin a few seconds after the player defeats the prior one, but roughly every three waves on all bar Nightmare difficulty, the player is given a break where they can set up traps and initiate the next wave when they are ready.
