River cannot exactly be explained as a "weak" weapon. Matter of fact, it just plain isn't one. River can do it all: Spread wide enough to cover large areas, do a great deal of damage to one or more tanks, and remain easily accessible as a weapon you'll unlock rather quickly. Twenty large projectiles scatter about to deal 8 damage a piece for a monstrous impact. Given its high spread, it's best to fire this weapon at 50-55 degrees, otherwise the weapon will not concentrate much firepower. It is to note that this weapon will never achieve its full damage under most, if not all circumstances.
