In Deus Ex: Human Revolution for the PC, PS3, and Xbox 360, you start off with an inventory size of 8 by 7 slots. You can increase this size however up to 14 by 7 slots by spending three praxis points.
There are three inventory upgrades that will expand your inventory 2 by 7 each upgrade. If you look at the Cybernetic Arm Prosthesis, you’ll see three Carrying Capacity Augmentations. Upgrading all of these will give you the max inventory size possible.
I find this fairly handy, especially if you like to have more money available. This will let you carry more weapons during your missions, in turn allowing you to sell more of them for a profit.
Also, if you’re a combat type, this will allow you to carry around more guns and ammo without having to search the area as much for the ammo you’ll eventually need.
