[2] Computer Gaming World in April 1994 said that "SubWar 2050 is a product with an identity crisis.

It wants to incorporate sophisticated physical models of the type you'd expect from a true simulation, and yet it wants to have an action game's visuals and pace", citing its including thermal layers, making them "largely irrelevant" with visual-oriented combat, then only providing unsophisticated short-range torpedoes.
