Sakamoto is one of the world's top players of BTOOOM!, an online FPS whose distinguishing feature is that your only weapons are bombs (of various types : contact-triggered, timed, etc.).
I mean, let's just put it out there: Does this game feature Bomb Jumping as a mechanic? Because that sort of thing seems to be an inevitable development for any game that features explosives anymore. (And it would be morbidly hilarious to see somebody try to replicate that sort of thing.)
