From OpenLieroX Wiki
Modern Warfare is a instagib mod. It was created by Scazzarus with help of other members at GU. It is popular for its flashy graphics, and over powered weapons. Most common setting picked is Mortars. Mortars is usually played by newcomers to the game. Though there are some long time LieroX players who play the setting on occation as well. Mostly Mortars is not considered a good setting among many long time LX players, which again lays out a conflict between new and old players.
Another setting is the limited version for this game. MW Limited which is played in 100lt with many weapon bans.
