Jack Cooper is a rifleman who inherits a titan called BT-7274, and the campaign that follows is a series of ideas other games would build a whole game around. Effect and Cause alone is worth the price.

Movement

Wall running, double jumps, slides that chain into each other. Pilots move faster than anything in the genre, and then they call in a twenty-foot robot.

Titans

Seven, each a different class. Ion's laser, Scorch's fire, Ronin's sword. Riding one is a different game.

Play on PS5

Runs on PS5 through backward compatibility, and people are still playing it.
