Remember the defense drones that flew around in Marathon 1? The ones that were on your side? Well here they are and ready for Infinity..slightly modified but a great job to say the least. Comes with a Anvil patch, physics model that you will need to use to incorporate these into your maps, plus a solo map (based on the Lost Network Packets) containing the normal ones...not the berserk ones in Marathon 1. These guys are really, really deadly so be careful!!!!!!! This update fixes a few bugs and improves general behavior, and also tweaks up the map a bit. Updates can always be found at the authors web page.
