The XM25 Advanced Airburst Weapon System is like a grenade launcher, only with a super-high tech twist. It can be set to detonate accurately without impact. Yup, laser targeting will calculate distance to a target, so you can aim at the structure the enemy is using as cover, fire over it (or past it), then watch as the detonation occurs in just the right place to take out your target. Not even the Corner Shot can avoid this one. Bang.It already exists - so why can't we play with it yet?
Above: Think Bomberman's kick/stop command, only it detonates too. Awesome
