ROTT: The HUNT Begins is actually the shareware title (we provide the shareware version, due to the fact that ROTT is not abandonware) of the full game, ROTT: Dark War.
ROTT is actually the successor to Wolfenstein 3D, which was the first game that lit up all this first person shooter genre, a genre which is most popular, even nowadays.

Rise of the Triad is a high quality, fast scrolling first-person perspective 3D action game. Graphics are on par with DOOM. It has destructive enemies and lots of them, an arsenal of weapons from simple pistols to missile launchers, life-preserving armor, traps and ambushes galore, and the ability to play by modem or network.
