Like Bioshock, your "weapons" are a combination of "guns" and psychic abilities, which can be upgraded as you progress through the game.

Theres so many possibilities to do every quest given all of the crazy upgrades, weapons, and powers you can get which likely will have me wanting to replay it when I finish

These are all vulnerable to bullets/wrench attacks, so the Shotgun and pistol are highly valuable weapons to have

Learn skills, collect objects and craft items/weapons if you want, figure out how to reach objectives using clues,defeating enemies, reading emails, finding the right weapon

Great visuals, the story will surprise you in a good way (no spoilers), cool weapons
