Invasion Force is a text-based strategy video game created by Robert Arnstein and released by Radio Shack in 1979 for TRS-80 computers. It is a TRS-80 version of an earlier game Trek-80 that was set in the Star Trek universe. All the Star Trek associated terminolory and themes were removed due to legal reasons. The gameplay of Invasion Force is similar to Mike Mayfield's classic 1971 Star Trek game.
