I have been trying to find some good B26 compatible zombies and something that gives you gold that you don't need to place at the beginning of a mission. Any help/links?

Mod the stone to have -10000 value. (Base.rte/some other stuff, go find it yourself, it's good practice.)

As for the zombies, isn't zombies 2009 still compatible? Or at least made compatible by somebody?(check the last few pages)
