PRIMARY: CHEMISTRY
SECONDARY: BIOLOGY
BOOKS: KILLBOTICS, PROGRAMMING
Also maybe: some kind of mind control science
=Performance altering drugs.
Plan:
STAGE 1: Develop better-than-conventional, but not too good, performance altering (improving) drugs. Sell en massé to THE GOVERNMENT, nice and legalish. Simultaneously, develop consumer electronics with the aid of KILLBOTICS. Housework Robots, or something (hooverbots, automated ovens, ect).
STAGE 2: In secret, improve performance drugs, in two lines: Line X, an improved version of the mass-sale government drugs, with an additional component: some form of mutagen/mind control/poison, which requires activation.
And Line Z, a more risky but vastly improved performance drug for the use by your minions in STAGE 4
On the consumer electronics front, develop (in secret), vastly improved version of the previous product(s), with integrated activators for the secret component of Line X.
STAGE 3: Release Line Z to the government. Get them hooked (really hooked). Also release Consumer Electronics+.
STAGE 4: Declare war on the world. Deploy MINION armies. Activate Line X biotoxins, by means of the wide spread Consumer Electronics+.
STAGE 5:
?
STAGE 6: PROFIT
The point is, I vote for CHEMISTRY for primary science.
