If you can't find the solution to a puzzle, or need to find the path forward, get as high possible and survey the land. Or, don't forget about chrono ping (defaulted with down on the D-pad or Mouse 3).

Treat this game like Bioshock. If you want a big amount of the upgrade material, search every nook and cranny. There isn't as much items as Bioshock (way less in comparison). WATCH out for "no going back" points. It takes time to recognize these. Usually if you feel the story is progressing, or there is a drop off, you want to stop and go the other directions to explore.

You can pick up far away items with anti-gravity.

I would highly suggest you play the Bioshock series. (Not needed to play this game, but it is a great series).

Items:
This game uses all three item dump techniques (some are popularly used terms, some are terms I came up with, some are terms someone else has come up with and aren't popularly used, I don't remember which are which).

• Boss Fountain: The game loads you up on items before entering the boss fight.
  
• Boss Sink: The game loads you up on items in the area with the boss fight (during the fight itself).
  
• Boss Drain: The game loads you up on items after the boss fight.

[You can only carry 2 weapons at a time (apart from the two special weapons, the RL-7 and the Seeker), so you should try out the different weapons and pick which two you like most before you start upgrading weapons.]

[The Seeker and the RL-7] ... [don't replace your other weapons].

Enemies getting too close? Use a shotgun or other UPGRADED weapon.

You can age items as you hold them with anti-gravity. This seems more of a time saver and interesting tid bit. I know for me, if I have to do this a lot, aging something, then picking it up, then putting it down, then aging it again, can become mundane. Your preference.

THIS SECTION IS DEVOTED TO PREFERRED GAME ADVICE FROM COMMUNITY MEMBERS, RATHER THAN GENERAL GAME PLAY ADVICE

[Hold onto the Seeker and the RL-7 for as long as you can. They don't replace your other weapons, allowing you to conserve ammo without dropping either of your guns.]

[It's not worth buying more than 1 or 2 levels in TMD power increases unless you find yourself constantly running low on power.]

[The extra oxygen hero perk is not worth buying.]

[The extra sprint hero perk is definitely worth buying.]
