Oberkommando is a Garry's Mod minigame. You can fight as the Combine or the Resistance, which each come with their pros and cons. However, Oberkommando 2 adds two new factions: the Zombies and the Antlions. The strategies for the Combine and Resistance are the same, however, these new factions need different strategies.

Zombie Strats:

1. Spam Poison Zombies.

2. Spam Zombines.

Antlion Strats:

1. Spam Antlion Guards or Guardians.

There is no efficient way for other factions to counter this, except for the Combine.

2. Spam Antlion Workers in the frontline.

Since Zombies are the undead and Antlions multiply rapidly, they spawn endlessly.
