Honestly, I've never played the game, as the oldest computer I have is a 98, and that doesn't even work well anymore. This is based on the comic. I picked up a copy of the Indiana Jones Omnibus that contains Fate of Atlantis, Thunder in the Orient, and Arms of Gold last time I went to a bookstore.
Put him in a white suit if you can, as that will make him look better. But nice idea! I should start making MOCs from the game, but I can't remember much because it's been a long time since I've played it.
