Rorie's Birthday Mod
President Bush in Wepons of Maths Instruction!, commonly known as Rorie's Birthday Mod and also called Commander Bush, is a Keen 1 mod created by Levellord as a birthday tribute for PCKF member Rorie. It features slightly edited Keen 1 levels with more enemies and hazards and is filled with political satire. The player controls then U.S. President George W. Bush, who appears in the form of an ape. The mod can be played with two different patch files, "Bush" and "Kerry", yet the only difference is that "Bush" features a custom palette.
