The Ghastleybriar Zoo Incident is a third-person action platformer developed in Source over a period of six months. The game depicts the epic struggle of Edward Mump, zookeeper, as he attempts to return the Ghastleybriar Zoo to its former state. Armed with only his trusty sack, Mump scours the zoo for bizarre critters to recapture. During his quest, he encounters cowardly Oddbobs, mischevious Grummies, and furious Rumpuses on the way to a climactic encounter with the terrifying Umbuggler. In developing the game, the team strove to create a very unique personlity influenced by the works of Edward Gorey and expressed through characters, environments, gameplay and dialogue. To this end, the team used a cartoonish, exaggerated art style with a sepia shader to recreate the look of a silent film. With The Ghastleybriar Zoo Incident, the team created a fun and unique title that is bound to be a great experience for gamers of all types.
