Portal 2 Sixense Perceptual Pack

Portal 2 Sixense Perceptual Pack is a standalone expansion pack for Portal 2 developed by Valve. It is mainly focused on the developers that are using the Intel Perceptual Computing SDK and a Senz3D depth camera. The camera is required to play the title.

The game features no plot whatsoever as it was developed as testing grounds for Intel's technology.

Gameplay

The core gameplay is the same as in the vanilla Portal 2 game. The players pass testing chambers using an Aperture Science Portal Device. This device creates two portals: blue and orange, which can be passed through by the players freely. The Portal Gun can also lift objects with its integrated gravity module.

The objective of the player is to reach the exit of the testing chamber by solving an environmental puzzle. For example, the door must be opened with a button that is triggered by a heavy crate. The players have to reach the crate first and somehow get in on the button for the door to open.

With each level, the difficulty of the environmental puzzles rises a bit with the addition of new elements and the increasing size of the chambers.

There are seven maps present in this map pack, specifically made for the use of the Senz3D camera.

Sixense technology

Sixense is a technology, that is developed by Intel. It allows the players to interact with the in-game objects using a special depth and gesture camera that is communicating with the game through a special API.
