Scooby-Doo! First Frights is a 3D linear platformer with light puzzle elements, and the gameplay and interface are highly reminiscent of TT Games' Lego game series. Players can choose to control either Scooby-Doo, Shaggy, Velma, Daphne or Fred. Scooby has a sausage string to hit with, blocking capability, and the ability to crawl into vents. Shaggy shoots with a slingshot, has blocking capability, and carries a yo-yo to grapple with. Velma throws books, has blocking capability, and can activate machines. Daphne has hand-to-hand combat, flying kick, and can climb up poles. Fred has hand-to-hand combat, stun bombs, and super strength to push crates and activate the handwheels. Each character has 2 costumes unique to each episode, and one obtainable with a code, with different powers and weapons.[6]
The game's 22 levels are separated into four "episodes." Each level has a clue, and at the end of each episode the player must choose who they think the villain is, based on the evidence they have gathered. Trophies and costumes are rewarded for doing certain tasks. The game can also be played in multiplayer co-op.
