Open original on X

Opus 5.5 is AGI. Here is the BO2 Zombie game it made. This was by no means a one-shot and still has some rough edges, but this game feels as close the original as I remember. Insane. Everything in this other than Audio was generated by Opus 5.5. This took about 12 hours and cost more than I would care to say lol
