If at particular spots the player falls from a certain height to the ground, they will be catapulted up again, although no jumppad is present (the technique is named overbounce). Overbounces can be combined with weapon techniques. The "DeFRaG" mod includes an "overbounce detector", a tool that helps the player to identify locations in maps where an overbounce is possible. A variety of overbounce opportunities has been discovered, made into techniques, and have been named accordingly: vertical, horizontal, sticky, diagonal ("weird"), zero-ups diagonal, and slippery diagonal overbounce.
