Launch Shadow of Chernobyl

Just self explaining.

It's recommended to solve this task after launching Clear Sky. (#382)

Status:

• Pre-alpha (same as alpha, but in a separate branch, and no official support claimed)
• Alpha (many bugs, crashes, don't expect that you can finish the game)
• Beta (bugs, crashes, but it's possible to finish the game)
• Release Candidate (there are minor bugs, from a few to none crashes, game is stable finishable)
• Release (game is stable)

      • This problem is linked with A-Life's group states
