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
- The bosses are bullet sponges. They are not, however, explosive sponges. A bunch of mines/ grenades / gas canisters will ruin a bosses day.
- On the same note, the Typhoon augmentation ruins bosses in 2-3 activations. It's also instantaneous and makes Jansen invulnerable for the duration.
- The non-lethal takedown is the most xp efficient way of dealing with enemies, at 50 xp per downed bad guy (125 for two guys at once with the double takedown upgrade). The next most efficient way is a headshot from the tranquilizer rifle (30 xp for a non-lethal takedown + 10 xp for a headshot). Whether you're going for the pacifist achievement or are trying to maximize your praxis kits, these are your best options.
- Hacking basics: capture the nodes that are unlikely to be detected first, and if you are detected disconnect and try again. Once you have to start hitting nodes with high detection chances, fortify everything you've got as you start the capture process, and try capturing / fortifying several nodes at ones before the trace starts. A good hack is a mixture of planning out your path to have as much stuff in the bag before a trace starts as possible, and frantically juggling your capture and fortify options ones the trace starts.
- !SPOILER WARNING! The third boss will counter your takedown attempts and do a lot of damage - UNLESS he's jumping over a wall as you do the takedown, in which case it's an instant win button.
