Aeon of Strife v1.2:

There are several physics files in this package:  'STANDARD', 'FRIENDLY', 'VENGEANCE', and 'RAMBO'.

'Aeon of Strife - STANDARD' basically makes most enemies attack each-other as well as you.  Robotic characters (Drones, Juggernauts, and A-BoBs) will attack anything and everything, including each-other.  S'pht Compilers will not attack you unless you attack them first.  F'lickta will not attack S'pht Compilers or S'pht K'r Defenders, and vice versa.

'Aeon of Strife - FRIENDLY' is the same as 'Aeon of Strife - STANDARD', except where none of the aliens will attack you.  Think of yourself as a neutral reporter.

'Aeon of Strife - VENGEANCE' is the same as 'Aeon of Strife - STANDARD', except where BoBs, S'pht Compilers, and S'pht K'r Defenders are hostile to you and to each-other in a massive free-for-all.  Yoink!

'Aeon of Strife - RAMBO' combines 'Aeon of Strife - STANDARD' with the sample physics model 'Rambo XXXIII', which makes all the weapons more dangerous.  Basically, one of the best cheat physics ever.

Drag the physics files into your Aleph One folder.  Open up Aleph One and go to Preferences.  Select 'Environment', then click on the text just to the right of the word 'Physics' - if you haven't modified the physics previously, this word should be 'Standard'.  A menu should pop up.  Somewhere you should see some physics files beginning with the title 'Aeon of Strife'.  Select the one you want.  Now open up a map that doesn't have merged physics.  Voila!

Cheers,
Perseus
