I was playing as Orks, since many people don’t know how to counter a green tide of slugga boyz. It was 3 vs 3. We were getting our asses kicked. They pushed us back to our bases. My base was closest to the enemy, so they were attacking me.
I noticed that my Weird Boy was fighting everything that came near and was still alive. Somehow he glitched and whenever he got hurt, he would regain full health. He fought and killed a Great Unclean One and was fighting a Baneblade. Unluckily the game ended before he destroyed it.
