Before From Software became famous for Demons’ Souls, they were creating first person action role playing games for the PsOne. Shadow Tower is one of the precursors to the popular Souls series. While the presentation may feel dated, From Software focused on the atmosphere of the skeleton filled dungeon.
Agetec saw promise in From Software and localized many of their games for the West. It looks like their English version of Shadow Tower will be re-released in the West as a PsOne Classic since the game was re-rated by the ESRB with Sony Computer Entertainment as the publisher.
