Find a rookie's location in memory by customizing his appearance. Note that the options start at 0 in memory, so they'll be 1 less than the displayed number. XCOM uses 4 byte hex to store data, and Cheat Engine displays it in big endian byte order, little endian bit order (I have no idea why, I can't imagine it's actually stored like this in XCOM) - e.g. the number 20 in decimal is stored as: 14 00 00 00 in my display on cheat engine. On to the good stuff.
I was wondering if anyone could link me a good cheat table for XCOM enemy within. I'm looking for something that can add engineers and or scientists. I know I can edit ini files or use console commands so I might end up doing that but it would be nice if I get something easier to use b/c I'm pretty dumb when it comes tot hat stuff
