Falls do not damage you, instead the higher the fall, the greater the impact once you touch ground.

You also have the ability to use weaponry found in the game. Military units deployed to stop you are easy pickings if you're looking for a fire fight. Alex can also hijack vehicles, pick up and launch vehicles, and use helicopters.

Health is regenerated by consumption. You won't find any health packs in this game. You need to absorb enemies to regain health. Some enemies will grant you larger amounts or regenerative health than others.
