Units can steal one of enemy weapons when kill it. Chance for weapon stealing is higher when killed unit had higher lvl than the one who killed it. Chance for each lvls difference: -1 lvls (and less) - 20%, 0 lvls - 30%, 1 lvl - 40%, 2 lvls - 50%, 3 lvls - 60%, 4 lvls - 70%, 5 lvls - 80%, 6 lvls (and more) - 90%. It works for all weapon specials from mainline era. Weapons can be dropped on a ground with using in unit menu (right button on your unit which you want to drop weapon) dropping weapons options. Oos are no longer expected because code isnt base anymore on sides controllers (ai/human/network).
It's playable with weapon specials from mod Recruit Bonuses v0.2.1 and Chaos Maps v0.4.1. Go get it now!
