This is an add-on to make the Fun Mod compatible with the 0.5 beta 2 release of the Tyranids mod and the Chaos Daemons mod. You need to install the Tyranids mod and the Chaos Daemons first to use this...
This is essentially the Chaos Daemons Test and Version 1.84 Tyranids Compatibility add-ons bundled together with a module to use them both at the same time.
