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)

Tasks:

• Filesystem:
  • Support both WW and RU encoded archives (efdd646 and 1d92cff)
  • Read archives from game root folder (26841e3)

• Animations
  • Different animation names
    • Crow
    • HUD uses anim_ prefix instead of anm_ (CS/COP standard)
  • Missing animations
    • Dogs
      • This problem is linked with A-Life's group states
• Old HUD (hands) system (2c0c123)
• AI
  • Read game.graph and level.gct (6b30ac3)
  • Mutants
  • Group states use set_current_animation() instead of animation manager
    • This makes us harder to fix the problem with missing dogs animation. Group states should use animation manager too.
