Crysis is a small series of shooters, the first part of which (like the third) at the time of its release became a real breakthrough in terms of graphics: the picture quality is cited as an example by some fans and developers even now.
The plot of Crysis begins with the fact that an ancient alien spaceship was found on an island near the coast of China, which the main character sets off to explore. Its main feature is a high-tech nanosuit that works in four different modes, which makes the protagonist stronger, faster and tougher.
Regular enemy soldiers are sooner or later replaced by alien troops, and the main character has at his disposal modifiable weapons, vehicles, an interactive environment and other interesting features.
