A "magazine" that has 300 rounds is not the kind that you read. It is the magazine for some time of weapon. A 300 round magazine would describe the capacity of the magazine. In other words, how many times the weapon can be fired before it has to be reloaded (change magazines).
That depends on the type of weapon used to fire it !
Black holes are round because they are formed from dead stars and white holes. As you can guess a star is a sphere and that is why black holes are round.

No. You can't upgrade an upgraded weapon. You can; however, go to the weapon box and get another normal weapon (doesn't matter if it's the same type of weapon) and upgrade that normal weapon. For example: you can upgrade a weapon, run out of ammo, go back to the weapon box, get the same weapon again but in normal form, and upgrade the new normal weapon. You can also pack a punch as many weapons as you want in a single game but you can only have two weapons at a time. SpiderBite from NextGenTactics pack a punched 15 different weapons in a single game.But I Pack-a-Punched ALL the guns in one game. By the way, I got to round 67.I am IProSyndicate
