CS2 update, August 20, 2026: Boulder and Poseidon map updates

What changed

\Boulder

  • Updated to the latest version from the Community Workshop (Update Notes)Poseidon
  • Updated to the latest version from the Community Workshop (Update Notes)\
  • Fixed a case where player speed was too high when moving against walls.

What it means for players and servers

Two Community Workshop maps have received updates. Boulder has been synchronized with the latest workshop version, while Poseidon received both a sync update and an important movement mechanic fix - player speed when moving along walls is now normalized.

For community server administrators, this means these maps will receive their fresh versions upon next server update. If Boulder or Poseidon are installed on your server, it's recommended to restart the server or revote for these maps to apply the new versions. The movement mechanic changes may slightly affect server balance and gameplay flow.
