Blank Flag

The Blank Flag is a special structure that only appears in Assault and Capture modes. In Capture gamemode, the Blank Flag is immune to all damage but may be captured by an Engineer; while in Assault gamemode, it has a large health pool but cannot be captured. Destroying or Capturing a flag will cause its owner to be DEFEATED immediately, so protecting your own Blank Flag is a must. Even the A.I.s will wall their flags up.

The Blank Flag is immune to Chrono Legionnaire's weapon, cannot be buffed by Nanocoat Regulators, and may not be Chronolifted to other places.


Behind the scenes

  • Prior to version 3.3.5, the Chinese flag used the apperance in reality, different from the Mental Omega's exclusively-designed, fictional flag (see here). Its artwork was also rougher.
  • Prior to version 3.3.5, the shadow of Japanese flag was incomplete, it only has the part from the flagpole. Its artwork was also rougher.
