'Double Up' is a 2D freeware mini game collection series for PC. The main point of the game is to tackle conventionally easy games with a twist.

The game presents the player with a main menu with a series of games to select. These games resemble racing, Pong, space invaders, and the like.

However, the player must not play these games just by themselves. They must play two iterations of the game at the same time, in split screen mode. Score, Health Points and any such values are shared between the two screens. Likewise, defeat in one screen means defeat in the other.

Playing games in this way adds unconventional difficulty to simple formulas and assists in developing dexterity.

Controls are fully customizable, so that the player can tackle the dual screens comfortably.

The game possesses an online multiplayer mode that can be played with strangers or friends. In this mode, both screens present an unusually hard iteration of the games that require the player's full attention. Each player would tackle one side of the screen, and work together to complete the tough levels!
