The depths return — rebuilt from the ground up
TriSoft's pioneering 1994 raycaster is back with a brand-new native engine. It's the same descent into the Zendle Mines to free the men of Ora from the Ri — the authentic levels, art, and enemy AI you remember — now running natively on modern Windows, no emulation required.
▶ How to play: press Play and choose "Play new_engine_BETA" from the launcher to drop into the new engine. This update is in beta — expect a few rough edges, and use the in-game bug reporter (F11) if you find one. The classic DOS builds are in that same launcher whenever you want them.
▶ Controls: the game starts with the original scheme — arrow keys to move and turn. Prefer WASD and mouse-look? Switch schemes or rebind every key in Settings → Controls.
