Deus Ex: Human Revolution

- When Sarif offers you a choice of weapons, I recommend the tranq rifle (choose nonlethal-ranged). It's the only scoped weapon you'll get for a while.

- Contrary to what the tutorial implies, you don't have to sneak up on someone to do a takedown. Also, unless you are roleplaying an asshole, there is no reason to do a lethal takedown, ever.

- The shotgun is a rape machine, even without the upgrade.

- To disarm a mine, hit walk, then crouch-walk up to it and use it.

- The EMP shielding aug actually makes you totally immune to electricity, so you can walk through electrified water and such.

- When hacking, if you capture the red security node, the hack succeeds and you automatically get all the bonus nodes. It's not always possible, tho.

- Yes, there are some useless augs. The stealth enhancers and hacking analyzers are all total crap, while the flash suppressant, gas immunity, and sprint boosters are marginal at best.

- If you plan to do a completely non-lethal takedown run of the game a) bosses don't count and b) the intro where you only have a gun, it tells you how to kill people, and gives you no non-lethal options does count.

- Your last unit of energy automatically recharges, but only the last unit. Getting the faster recharge aug just makes that last point recharge faster.

- Sidequests not finished before leaving a hub are gone forever. Do them before moving on if you want to do them at all. There are typically 3 per zone.

- The casie aug unlocks a couple more dialog options so if you wanna talk your way out/into stuff consider getting it.

- Breaking through walls unlocks a lot of new routes in the game so its surprisngly not worthless
