Critical Depth
SLES-00136
Initially Released 1 December 1997
Critical Depth is a vehicular combat game developed by SingleTrac Entertainment Technologies and published by GT Interactive Software for the PlayStation, sharing its engine and concept with the Twisted Metal franchise but transposing the action entirely underwater, with all combatants piloting submarines across a series of arenas.
The database catalogues a single PAL variant of Critical Depth. The release covers the UK, France, Germany, Italy, Spain, and the Netherlands under the Original release type, with the earliest PAL release date recorded as 1 December 1997. The variant is housed in a Full Jewel PAL case with a single disc in English, and carries a hologram on the case. Loose paperwork includes a GT Light Purple Registration Card, which is a notable inclusion for collectors tracking GT Interactive paperwork variants. No case stickers or bundled demo discs have been documented. SingleTrac’s underwater spin on vehicular combat makes this a distinctive niche title, and its single catalogued PAL variant with the GT registration card makes it a satisfying find for completists.
