Pssst is an action video game developed and published by Ultimate Play the Game that was released for the ZX Spectrum in June 1983. In the game, Robbie the Robot has to protect his plant (a Thyrgodian Megga Chrisanthodil) as it is attacked by various insects, each of which needs a different repellent to neutralise it. Pssst was the second game to be released by Ultimate, after Jetpac.
The game was written by Chris Stamper and graphics were designed by his brother, Tim Stamper. The game received positive reviews from two publications upon release, with critics mainly praising its presentation and gameplay.
Gameplay

The game is presented from a single, 2D perspective, and revolves around Robbie the Robot's objective to defend his plant from interstellar space slugs, leeches and midges. The plant grows from the bottom centre of the screen, and spray cans containing three different pesticides are located on ledges on each side of the screen. Bonus items such as fertiliser and fly swatters appear on unoccupied ledges which will increase both the players score and the plant's growth rate. The game used the common technique of sprites and allowing them to be placed atop each other, which often overlapped colours on the screen causing attribute clash. Pssst was also able to run on the 16K version of the Spectrum.
