Deus Ex 2: Invisible War

• The levels are divided into small parts which is 1/2 of a typical Half Life 2 map. This is a major drawback as the loading times are horribly long. Be sure to drink a lot of alcohol-free beer so you can take a wee while entering a new door. That way, the time is not all wasted.
• Once you enter the ice level, you'll basically never need to hack a computer again. Thankfully, the game allows you to respec.
• Electrostatic Discharge allows you to scramble robots and disable lasers with your melee. At level 3 you get to turn giant robots to your side in one hit.
