It's not so bad imo that the pre-order mission would have probably given 1-2 extra points (plus i dunno, you migh be able to max without it). So progression and what you unlock is still very meaningful as you play the game.Д®dit: sorry my bad, I didn't notice the parts you bolded. And of course you aren't playing the game with everything maxed out either. The game rewards exploration and finding as much stuff and as much hidden stuff as possible. Why? Most people won't even come close to the amount of points I have, much less maxing out the tree. If this is true, that's a fucking disgrace. (which is kind of a bummer that it's not in the standard game)

The game was designed in a way that it's possible to completely 100% max your augs, if one finds every single secret and hidden areas as well as does that extra content. Praxis kits in Limb clinics are limited to 2 per clinic for each time you visit the said: According to that screenshot, you have enough credits to max everything out right now. I'm missing something here maybe? Admittedly I'm still very early in the game, but unless you're specifically talking about augmenting via game XP only, you can buy Praxis kits at a LIMB clinic for 5,000 credits apiece (unless the price goes up at some point).

I'm sure its possible, do you get XP for taking down citizens?
