Big fans of the Halo series try to recreate one of the games from this series on the CryEngine.

Is not clear what kind of game from the Halo series... perhaps one of the last.
This attempt of Halo recreating is codenamed Project Contingency.
And it is unclear if this insanity will be materialized.

However, on CryEngine  there are many examples of attempts to recreate the different games, taking into account the ease of working with this engine and its nice graphics.
And these attempts are only good lessons for beginners, which are well learn how to create games.
I really hope that from this group of beginners in the future will appear the good developers. :)
