Croc: Legend of the Gobbos
Croc: Legend of the Gobbos is a 1997 3D platform game developed by Argonaut Games for the PS1. The game follows the titular crocodile as he traverses various levels to rescue his adoptive species, the Gobbos. While the levels themselves are linear, Croc must still explore them thoroughly to rescue six Gobbos in each stage, which will allow him to unlock more levels and reach the final boss.
