"PUNT is a first-person environmental puzzle mod using Valve's Source Engine. Players must solve puzzles using the brand new Punt Gun to activate and deactivate different objects. As a spiritual successor to the Portal mod 'Blue Portals,' the mod focuses on different kinds of special cubes. Flip gravity, freeze boxes in space, or even make them explode! You can even 'punt' the floor to bounce around the room!"
