I don't remember it very well after 21 hrs of gameplay but i think you get the ending (it doesn't show in the endings gallery tho) 'not a sucker' or something along those lines
each weapon has a dif slot, for example the pistol (and i think all small weapons) goes in the first slot, most ARs/SMGs in the second and most shotguns/rocket launchers in the 3rd
That was a great game! But if you spam spawn tvs at the start of a level you can go inside the floor and stand on the bottom of the floor, so maybe you could make it so you can't spawn tvs at the start/have a certain radius where you can't spawn tvs?
