Who would want a game to Gantz?

I wish it was a third person shooter. The main mode would be to find, just in this room with Gantz and be catapulted into the arena along with 7 IA, to defeat the aliens on duty (very difficult to break down). Obviously, the arenas will always represent a Tokyo night and be huge and very interactive with all the facilities subject to collapse based on the damage received (a bit like Red Faction). They should have many hiding places, such as garages, car parks and so on. Important to the growth of the character, where there should be a system-wide growth Fallout type, where each level you gain the ability to choose a "perks" between the super jump, powerful punches and all the features of the manga, and every five levels you acquires a weapon. Speaking of weapons, it would take more traditional weapons, once reached the 50th and final level of experience, the weapon of the soul that all pulp. We carry only two weapons at a time, a firearm and one to trap the opponent. Health should be divided into 4 segments rechargeable but only in certain places called "hiding" and visible on the map. Once in a secret can be charged only one segment'm standing still ten seconds. 7 The IA will be replaced at any time by a human player via splitscreen or online. Besides the story mode only it would take a team-based multiplayer (human vs alien) with a ratio of 15 vs 3 ... It would be nice ... but it's just an idea ...
