User blog comment:Le Rottweiler/How do these 2 powerups function?/@comment-1496755-20151206145242/@comment-1496755-20151209100425

For me, themore realistic version is that the cells are in Ranger's backpack (let's assume he has one) and are connected to the Thunderbolt with cables. The weapon itself is smaller than the cells (or at least it seems os in the game), so inserting them into it would be difficult.

The player model does not really have a backpack, but it probably should, since he has to carry all this ammo (and the 4 runes) somewhere. And in Q2 there is a backpack powerup that increases your carrying capacity for all ammo types. Makes you wonder how big the player character's pockets are if he could carry all this stuff without the pack. There is also an inferior version of the powerup, the Bandolier, which (realistically) does not increase carrying capacity for grenades and rockets (they can't fit on it).
