'''''Mission Genocide''''', alternatively titled '''''ZTB''''' (for ''Zap the Bastards'' and later ''Badstars'' [http://www.dadgum.com/halcyon/BOOK/SHIRLEY.HTM]) on the loading screen and elsewhere, is a game for the old generation of CPCs, released on both tape and disc and compatible with all models.
The game is mentioned fairly often for its smooth and pixel-perfect vertical scrolling, which is done in hardware using the [[CRTC]]. It is also notable in using a very fast method of plotting sprites, which takes advantage of the 16 colours of graphical Mode 0 by using 3 for sprites, Ink 0 for transparency, and the remaining 12 as 3 duplicate sets of 4 colours for the background: the roles of these Inks are arranged according to binary logic so that sprites can be ORd onto the background and ANDed to remove them, a method that is much faster and more memory-efficient than storing a sprite and a masking table and then performing all the relevant masking operations between these and the background.
