ugh, what a useless deadweight loser the MC is... he has all those guns, infinite ammo, and any ammo he so damn well please, and in teh middle fo a coloseum full of seasoned warriors with real swords fully intent on killing him, and he is still to much of a pussy to actually shoot them, and teh weapons he use is wrong choice for the occassion as well, but what did ve expect? MC cant exactly be smarter then the author, now can he?
rubber bullets against fuly armored dudes like these guys would do absolutely nothing other then scare and suprise them for a bit at most, you'll need something far more powerfull then a freaking colt and submachinegun to actually stop them with only rubber bullets.
so much potential to this series, unfortunately wasted and lost on this incompetent fool...
