Evil Genius FAQ

Laboratory
  The lab is where you research all the cool gadgets and base enhancements 
  you didn't have to start with.  Unlock it by stealing the research machine 
  when it becomes available.  BE CAREFUL: Doing this will trigger an endless 
  stream of thieves until you build a fake lab, fake machine and let them 
  "steal it back".  

  Your old topside shack is a good candidate for the fake lab, and it'll just
  barely hold a fake research machine.  A topside lab nearer to the port (where
  the agents keep landing) would be better.  For your main lab, you'll want a
  LOT of space, all the stuff that goes in it is huge.  10x12 would probably be
  good.

  In order to enable research, you need the machine, a databank, and an 
  experimental gadget.  All the other stuff that goes in the lab are used in 
  the research process to create new technology.  See the RESEARCH section for 
  more on this.

  You'll also want to place this room far inside your base, and only after your
  fake machine has been successfully stolen.  Most stuff in it generates heat.

  The AI computer, Environment Chamber & Greenhouse become available after you
  make it to Island 2.
