It was obvious that Taito was inspired by Alien while making this. Also, they were one of the few third-party developers for the system who made quality stuff.
Port of one of my favorite Atari arcade games, though I have it on Midway Arcade Treasures. By the way, Tengen was the console-publishing division for Atari Games, inc. In addition, Atari was split into three separate companies when the Video Game Crash hit.
Super Space Invaders
This needs no further explanation.
Cloud Master/Chuuka Taisen
Hot B did a great job at porting this game, and this is one of the rare few titles that had FM chip support. (Only the JP version of the SMS had this.)
Possibly the only Master System game that had parallax scrolling.

One of the two Technos titles that were brought to the SMS.
And here's the other. However, II and III weren't ported to the SMS.
The other Irem port for the SMS.
