Alien Trilogy (Shareware v0.90) is for version 1.4. It has 4 levels and the file is 205KB in size. The file name is alientc.zip. It was released on July 26, 1997.

Alien Trilogy is supposed to be a shareware version (What is a shareware version of a free TC I wonder?) of the Alien Trilogy TC. The full TC is supposed to have all new enemies, this uses the original Duke3d ones. It has fair to good level design and poor gameplay. It is very dark in many places and much too hard. Fighting against new beasts with a pistol is just stupid. Anyway this is a space outpost style TC with some outdoor areas included. I just kept switching back and forth from god mode just to finish and review this TC. I rate it as fair with 2 out of 5 stars.
