I'm part way through Deus Ex: HR and am generally enjoying it a lot -- the original remains one of my all time faves and this one is a pretty worthy successor (particularly the amusing DeusEx-isms like the unnaturally large number of cardboard boxes in the world and the abundance of carefully labelled washroom facilities). But there is one gripe that is really bugging me which is energy: I currently have three cells and it seems that I can charge all three with energy bars but only the first one will recharge naturally. Energy bars are also quite hard to come by (certainly way rarer than 10mm ammo for example) so it doesn't make sense to charge up the two spare cells unless I have a particular usage in mind. What this means is that there is a real disincentive for me to use augs and instant takedowns as anything other than occasional one-offs for use in strictly one on one situations (or one on two if they are close enough together). I keep on getting into situations where I try to chain augs and takedowns (e.g. running in under cloak and then following up with a double takedown, or throwing a refridgerator and then trying to do a takedown as someone gets up) and run out of energy half way through. This is leading me to leave off that kind of gameplay and go for simple vent-crawling instead (run and gun not really an option for me, or at least not on hardest difficulty), which is a bit disappointing given that gameplay freedom is fundamental to the series. By way of comparison, I also have Batman:AA on the go and in that game (which is astonishingly well designed) whenever I try something spontaneously it usually works whereas in DX:HR it doesn't work unless I plan ahead and use up precious energy bars. Have I missed some important trick in DX:HR? E.g. a way to get all the cells to recharge naturally, or to reduce the energy used for takedowns etc so that you get more than one per cell.
