games similiar to Doom RPG

[blueagent1999]

i was a huge fan of doom rpg back then and i'm looking for games that are similar to it,

or more specifically, i'm looking for 2D/3D first person sci-fi RPGs that plays like doom rpg.

 

thus far i've found one called "SpaceMerc Liberation" which is a literally a carbon copy of Doom RPG, except the whole game is in russian.

then there's "StarCrawlers" and "Space Shock", both games closely resembles doom rpg's sci-fi and turn based aesthetics, though space shock has since become vaporware.

 

i've also looked into older games like HIRED GUNS on the Amiga, and Xenomorph on the Commodore 64.

 

anyone have more recommendations?

 

thanks!
