alright, quick thing that i want to pitch to you before i go to sleep
Speed Loaders
a Speed Loader is, simply, a pick-up item (you know, as in you have to walk over it to use it) that is used to instantly reload all of your weapons at once to maximum capacity. alternately, you can find it still in it's container (ala explosive or incendiary rounds in l4d2) and use it later. i would assume people would make the caseless speed loader more rare then the ones in the box, but that's just me
Ammo Bolsters
an Ammo Bolster is basically a pick-up (similar to a speed loader) that increases your ammo to 1.5x your normal capacity. YES, 1.5X. roll into battle with a double barrel shotgun with THREE ROUNDS in it! find a rocket launcher with ONE AND A HALF rockets to use! find an LMG that takes FOREVER to empty! the potential is limitless. does not come in a case.
the Medisyringe
the Medisyringe allows a player to heal themself or a teammate- using the LMB allows you to use it like a spear and heal your buddies, while RMB allows you to stab yourself with it and heal yourself (but for less then you would heal another player). the longer you let it sit without healing someone, the more it'll heal when you use it. healing someone for the maximum amount in one shot (100 HP, a full heal to a normal player) will give them a breif period of invincibility and speed that i like to call an Adrenaline Rush- about 5 seconds of chemical-boosted fury!
