Me and some friends bought the 4 packs last week for a LAN. Fun little game and justified for a new purchase, they did some cool new additions like the physic elements and they also changed alot of "traditional" stuff, some for the good, some for the worse (I hate the new ninja rope, the controls for it are awful

). Still, alot of fun and would recommend for Worms-fans. The classsystem is a fresh new thing and brings some more depth in teamcreation.
Still only 4worm-teams though :/ but the netcode is improved, nomore delay and "Waiting for players..." after each turn unless theres water or physicobjects moving during the pause.
