i guess this would be a cross between a traslocator and a sniper rifle even know the team is trying to make INF as real as possible i think a grappling hook spear gun to get to higher or lower places would be cool and would make for great stealth attacks. Emagine your lowering yourself from the top a high building you see a sniper inside you swing to smash the window and thow a knife at the snipers throat. I would be pretty shore that something like this would exist in real life.you could also use it as a weapon were you can shoot the enemy. It would also make for some very excellend assult maps!!! (COOL!!!! THINK ABOUT IT)
