"He annihilates aliens by shooting them"
Crysis is a first-person shooting video game that places the character in the not-too-distant future when the earth is being invaded by extraterrestrials after years of wars between humans. You're part of a special squadron of armed forces that tries to stop aliens while controlling the weapons of enemies who threaten to completely destroy the planet.
Crysis is one of the first video games that adapted its graphics to DirectX and demonstrated it for the general public with this video in which the new visual effects brought by DirectX technology could be appreciated.
