Due to this rather strange mechanic, having more than 2 energy units is actually a waste of your praxis points, if you have two you can simply consume an energy bar once the second energy unit has depleted and whilst having a third unit available can make this “juggle” easier it is certainly not required. We advise you always have 2 “stacks” of single energy supplements, the multiple energy supplement pickups are simply too bulky to carry around, and do not offer the flexibility of “unit by unit” usage. The main uses of more than one energy unit are when you need to “cloak” over a medium or long distance or when you need multiple activations of your Typhoon in short order. So it is best to play the game as if you only have one energy unit available and use supplements for emergencies only. This gets “expensive” quickly as energy supplements are in limited supply. To have a second, third or fourth unit available you must consume an energy supplement of some sort. That is to say only your “first” unit will recharge itself. Why? Because, whilst you can upgrade your energy “store” by multiple units, you only automatically recharge one of your depleted units. You must expect to play with a single energy unit for the vast majority of the game. Careful management of your augmentations is important…Įnergy: Deus Ex Human Revolution, as it stands, is brutal on your energy.
