IDW’s 2011 Infestation wasn’t a crossover in the classic sense, as the disparate characters didn’t meet face to face, but it did bring together some properties you’d never expect to see in the same story in Rashamon style, namely: Star Trek, Transformers, Ghostbusters and G.I. Joe.
Infestation is a comic book crossover published by IDW Publishing, and connecting various of its licensed and original series together. It was published from January to April 2011. It consisted of two book-end one-shots, Infestation #1–2, set in the Zombies vs. Robots and CVO universes, and two-issue limited series from the G.I. Joe, Transformers, Ghostbusters, and Star Trek universes. Also, IDW published a digital-only Pocket God tie-in issue in May 2011 which was included in the hardcover book.
IDW then released a four-issue epilogue series titled Infestation: Outbreak from June 2011 – September 2011. It picked up on the CVO after the events of Infestation and also introduced the events of the Groom Lake limited series into the same continuity of the CVO. IDW also published a four-issue follow-up series set in the Zombies vs. Robots universe after the events of Infestation, entitled Zombies vs. Robots: UnderCity.
