Breakdown

A vast underground complex was discovered in Japan. Unexpectedly, an entire
race of creatures, known as the T’lan, was found dwelling there, guided by a
mysterious being called Nexus. The humans built a research facility near the
underground complex, called Site Zero, and sent soldiers to protect the
researchers and ensure that the fragile peace between humans and T’lan will
last. As Derrick Cole awakens in a recovery facility near Site Zero, he fails
to remember anything from his past. Apparently, he was injected T’langen, a
fluid that was taken from the T’lan, which has unexpected effects on human
organism. As the war between the humans and the T’lan begins, Derrick must
first of all find a way to escape, with both sides being hostile to him,
unaware of the role he will play in the future of both races.

Breakdown is a first-person action game. Though Derrick can use firearms,
it is not entirely a FPS; much of the game’s combat relies on melee moves and
combos that Derrick learns, turning the game into a “first-person fighter”. An
unusual feature of the game is the completely physical interaction with the
environment, which strives to be realistic. In order to force Derrick to pick
up ammo, operate an object, eat food to restore health, etc., the player has
to physically move the controller, imitating corresponding real-life
movements.
