Persec, not to be confused with the TI cartridge called Parsec, is a game in which you have to defend the earth from an alien invasion.

An invader, intent on destroying earth and all in his way, randomly moves to the left and right firing at earth and your base as he proceeds down the screen. Zap him and his followers to score ad beat the invasion.

If an invader lands I think the earth is destroyed. But how effective this is I cannot say, as the program crashes at this point!

Blitz (screen title Alien Sabotage) is yet another game on the destruction theme. As a pilot of a crippled alien craft it is your task to clear a landing strip in a built up area in order to land safely. By using two keys alternately to fire, I was able to land every time.

The screen playing instructions for both games are clear and concise. Screen display and sound are good, but I lost interest in both games as there is no increase in degree of difficulty and play became repetitious.
