Exiting the unlockable Turret from Zombie Massacre on flat ground in the Courtyard Villa makes you fall through the ground, forcing you to noclip back up.
Place the Turret on the stone path by the basketball court (or anywhere seen in the video), Enter it, then exit it
I’d leave the turret. Simple as that.
I fell through the ground and into water underneath the map, and had to go into noclip to get back to the map.
I haven’t tested this on other maps, I just randomly found this and tried it in a few other spots. Notably, I did not fall through the ground while it was in the basketball court, or on an angled surface. I recorded a video to showcase, posting it through youtube because It doesn’t let me post the video file. Tower Unite Glitch - YouTube
