Blue Portals: Extended Play

 is a non-canon expansion for Reepblue's Blue Portals. It expands on the mechanics of Blue Portals and also introduces new elements, such as the Light cube. It is also the first mod in which the Punt Gun was seen and the only non-PUNT/Vectronic media where it also appears.

Gameplay
The gameplay has for the most part, not changed from Blue Portals, with the game being composed of puzzles mostly based on flinging and time-based puzzles. This entry introduces Light cube and the Punt Gun. The light cube functions like a rechargable battery, charging in light and only lasting for a certain amount of time, and the Punt Gun acts as a modified gravity gun that allows the player to propel themselves off the ground in selected spots. Reepblue would eventually try to develop the mechanic into it's own entry (See: PUNT)

Visual Style
The visual style of the whole expansion resembles the last few levels of Blue Portals: Expansive, Unfinished chambers with lighting coming from the sky for interesting lighting. Considering the date was being developed in, it is highly likely that the style in the expansion was heavily inspired by Portal 2.

Development
Not much information has been shared on the Development of, but the expansion was teased in the 4th Blue Portals Post-Release article and more information was given on the expansion until it eventually released in March 10th, 2011.
