I have no idea what really caused it but for some reason while doing the Spartan Ops mission Galileo I encountered a “little” glitch. I was solo and on Legendary, right after turning on the turrets I noticed alot of enemies on my map, however the area looked empty for the most part. Any time I jumped out from behind cover I was quickly killed. Upon looking further I saw guns moving on the ground, just floating it seemed, very fast, and very deadly. After about 15 minutes I noticed that the guns were not really floating, however the enemies were very, very, very small.
Elites, Grunts, and Jackals, were about 1/10th or less of the size of their weapons. This glitch made it impossible to kill anything without dying a ton of times because it was near impossible to shoot them at such a small size, let alone get a headshot on enemies such as Grunts or Jackals, the latter of which were nearly invincible thanks to their tiny shields covering 95% of their spec that was their body. This glitch happened to all enemies that appeared from the time the turrets were turned on, until the last 3 elites appeared. It was a very funny glitch, but sadly I can not record it in Theater as I had planed. In either case I wanted to report this and see if anyone else had anything similar to my problems with the mini-covie army.
