A few months ago, we got a closer look at The Rookie’s playable character in Ghostbusters: The Video Game, who, during production, saw a pretty drastic makeover and would eventually go on to record a small legacy by himself, starring in several comics and even getting his own action figure.

While the game was in the early stages of production, there was debate over exactly who should play The Rookie, with an initial push to hire a well-known Hollywood actor. After deciding that this might be a little too distracting for the player, and with the game’s developers, Terminal Reality wanting to keep production costs down, they would eventually settle on Ryan French, an associate producer at Sierra Entertainment, the original publisher of the game .

Along with French, Eric Schatz, a Terminal Reality level designer, was tapped to play the role of The Rookie, at least during the initial stage of production. Although some have claimed that Schatz was replaced because the character looked too much like Half-Life’s Gordon Freeman, i.e. black-rimmed glasses and a dark goatee, the use of Schatz’s likeness was always believe it was temporary as it was seen as just part of the green light build.

Today, somewhat surprisingly, a handful of images from the early days of development have surfaced online thanks to game designer Bob Cooksey’s Art Station account.

Cooksey did the modeling work for two of the game’s most memorable levels, Time Square and Central Park Cemetery. The images below provide early and unfinished concepts, along with a look at Schatz as The Rookie.

Since this construction was designed to be seen only by those in Terminal Reality, it’s no surprise that Time Square’s branding is made up of real-world products, including Samsung, Budweiser, Coca-Cola, Planters Peanuts, and month.

A notable billboard is that of Bloodrayne II, another game developed by Terminal Reality, on which Cooksey also worked.
