"Now for the changes, and here's where things start to get controversial. One of the most important recent innovations is the use of cover in first-person shooters, and Eidos has said they will implement such a system here. The difference is that the cover system in Deus Ex 3 will be used for stealth, allowing the player to hide behind objects when trying to evade enemies. Eidos has also said that the health of the main character will also automatically regenerate, owing to the biomechanical implants he's got installed."
