They most likely means the original Lethal Ape 3. You see, Karma (the person whose LA3 you're trying to revive), was not the first person to make a Lethal Ape fangame called "Lethal Ape 3" the first game called LA3 was created by Universal.Render.Pipeline (or Universal for short), however, the game got revamped, and the community didn't like the revamp, so the game got cancelled. It was brought back as "Lethal Ape 3 OG" as the pre-revamped version, but I think that got cancelled recently and idk why. And since this is on Universal's account, I think that's what they mean.
I understand which version they mean. I just decided to say that on my account I have a similar game, Lethal Ape 3, where the monsters are almost the same. By the way, I want to point out that this game was created by Karma and me, and Pinkhat also helped us, but he is no longer part of our team. It's just that when Lethal Ape 3 on the Meta Store started getting worse with its updates, I decided to revive the game: I turned the new version into the old one, and Karma helped me with that the whole time.
