Backpacks are a supplement to armor suits that allow you to carry additional weapons and assist items in Star Warfare: Alien Invasion. Backpacks work independently of armor; backpacks do not affect armor sets with their bonuses, and vise versa. That said, different backpacks allow you to carry more items and have special buffs as well, such as power boosts, speed increases, health regeneration, and occasionally an ability such as hovering. By default (start of the game) you can carry only 3 guns/assist items.
Weapons and items can only be used in battle if they have been placed in the backpack prior to entering any room. To place equipment into the bag, a player must access the Customize menu, and then tap the "Pack" button. This will bring up a selection grid of all the equipment the player owns, with the row of squares at the bottom of the screen representing the player's bag and any equipped items. Some backpacks allow the user to levitate and hover over any bosses poison
Each bag has a different limit on how many items can be stored in it. For example, a backpack with a capacity of 5 will be able to store a total of 5 weapons or assist items.
Backpacks make a return in Star Warfare 2: Payback, but no longer increase the amount of items you are allow to hold.

+Note: Recommended for people who don't like to buy ammo. Your energy still appears on screen, but it doesn't get expended when you fire your weapon while using this bag.
^Note: Immunity to ground hazards is a permanent effect. The F.L.O.A.T bag has the ability to activate a temporary +2 speed boost for 30 seconds.
*^Note: The STK.F will override the effects of the Jin.Jingle, they will not add together to give +30% power to the team
^^Note: This is similar to the F.L.O.A.T bag in its floating aspect, but it trades the speed boost ability and 2 bag slots for a +40% sword passive power boost.
***Note: Specific functions of the Dracula:
- Estimated Power Trade-off: -25% POW
- Proven HP Absorption: 65% of effective damage output when ability is not active
