Now, go to Activities.ini, and add away. Note: You will have to add the Includefiles from EVERY mod you want loaded; it's probably the primary reason I put all my mods into one pack.

To change what craft are delivered, use this basic guide: In each mod .rte, somewhere, there is a root instancename for what you want to mod into Activities.ini, and a root prop type for it.

Nearly always, this will be one of the following:

* ADoor
* ACDropship
* ACrab
* ACRocket
* AHuman
* HDFirearm
* HeldDevice
* TDExplosive

Most of the time, this is fairly self explanatory.

If it's a door, it's going to be an ADoor.
If it's a dropship, it'll be an ACDropship.
If it's a crab, OR a four-legged turret, it'll be an ACrab.
ACRocket is for rockets.
HDFirearm just means gun (held device firearm), so any gun mod will use this.
HeldDevice is what Shields use; specifically the Riot Shield.
TDExplosive is for most bombs, and all grenades.

So, here's what you do. Depending on the mod, the particle type will change. So, first, what you have to do is find the prop type. Generally, in the buy menu, this will be explained for you. The Actors tab covers AHuman and ACrab. AHuman also covers Robots, so don't make it ARobot in your activities edit. Craft covers ACRockets and ACDropships. Hint: Rockets have one engine, dropships have two. Shields tab has HeldDevices, Bombs has TDExplosives. Tools and Firearms are both HDFirearms.

So, then, you have to get the instancename, which is just the name of the mod. This is even easier; just look at what it's called in either the Bunker Editor or Build Menu.

Now, open Activities.ini, scroll down to the Grasslands activities, and mod away.

AddAttackerSpawn = <prop>
CopyOf = <instancename>

All there really is to it. Oh, and if you're curious, yes, you can make AHumans fall from the sky. Or HDFirearms.
