  • Map Changes:
    • Changed the location of the sniper hint at the front.
    • Added "wave_start_relay_noreset_1b" and "wave_start_relay_noreset_2b"
    • These relays spawn bombs that don't reset. 1b spawns 1 bomb and 2b spawns 2 bombs.
    • Removed wave_start_relay_endurance as it was identical to wave_start_relay_1b.
  • No mission changes.

rc12 (May 27, 2019)

  • stairs clip

rc11 (May 25, 2019)

  • Fixed nav_avoids

rc4 (May 14, 2019)

  • Map changes:
    • Remade from scratch
    • New Theme: Kill the robots as you defend the secret Mannco Chemical plant disguised as a biodome!
  • Layout changes:
    • Upper bridge near front was removed as it was not useful and only added clutter to the layout.
    • When players are pushed back enough, sniper bots will now spawn from a room near upper balcony, giving them access to the highground overlooking the biodome
    • When bots are pushed back into the pit while the left (lime) route is selected, it will take a shortcut back into the main route. This allows robots to return to the main path around 10~20 seconds earlier depending on the speed of the bomb carrier.
    • High ground near hatch was removed as it was not providing useful advantage to the players. The side room now serves as extra route the player can take when the main ramp is too crowded.
    • The small path that existed on right is now connected to the upper room for better connectivity of the area.
  • Reworked mission_start relays:
    • wave_start_1b allows the wave to be run with 1 bomb.
    • wave_start_2b allows the wave to run with 2 bombs. relay_endure_route_change when triggered, will change the route the bots take, pause all wavespawns, reset the bomb, and stun all small bots for 20 seconds. The wave resumes after the 20 seconds timer.
  • Mission Changes:
    • SnowySlaughter (int)
      • SnowySlaughter was renamed to BiomeBattle to fit the new theme of the map.
      • SnowySlaughter now uses wave_start_1b
