In Battlevoid Harbinger we currently has 2 game modes

Normal Edit

Normal game modes are the typical gamemode of Battlevoid Harbinger. The normal gamemode has 4 Levels. Three of the levels use a random species that chosen from Trolgar, Schillae, Wanderer, or Celestial races. The Final Level is the unknown race, which is very powerful and if outnumbered you will probably die, unless you have an OP ship (Armada, Harbinger, Valiant, Or Trademark). If you beat the final boss (A.K.A. 4 battlestations), you will reach the end of the game and the credits.

Endless Edit

Endless game mode is the advanced gamemode of Battlevoid Harbinger. It's pretty much the same as a normal gamemode, but with the exception indicated by its name:  it doesn't end at the final boss. Instead, it will loop through three random races levels and one unknown race level, after which your progress will not restarted but continued across the game.
