Dark Sector

• Save your money until you get the "save $X" achievement, then spend it on the best assault rifle and pistol you can. Then upgrade them both. What upgrades are up to you as long as you include the Enefron Shells upgrade. This makes your shells emit a gas that is poisonous to the mutant baddies (and also to you, so dont run through the gas, but its pretty shortlived) and makes it do a load more damage to them.

• Most of the puzzles are pretty obvious; If you are given a source of fire you are supposed to set the glaive on fire and then use it on something. Ditto electricity and so on. If you are given an ability then the next boss or puzzle will use that ability (And then in 75% of cases you will never use that ability again).

• The invisible boss is a pain in the arse so check a FAQ if you get stuck on him, otherwise just play it like a 3rd person shooter with a steerable weapon.

• All the weapons the baddies drop have a chip on them which makes them self destruct after a certain amount of time, the weapons you buy dont.
