World of Padman
World of Padman (WoP) is an open source first-person shooter computer game available in both English and German. Originally it was a modification for the game Quake III Arena titled PadMod created in the year 2004. After the source code for Quake III Arena was released, the game became standalone.
The idea is based on the Padman comic strip for the magazine PlayStation Games created by the professional cartoon artist Andreas ‘ENTE’ (German for "Duck") Endres, who is also the man who made many of the maps included with the game in 1998. The current version runs on an enhanced version of the ioquake3 engine, which is based on the Quake III Arena engine. Over the years maps have been revamped, bot play improved, killer-ducks kept hungry, weapons repolished, menu’s redesigned, and much more, such as new sounds, skins, secrets, effects, and power-ups! In all, there are 13 maps. Each supports up to 7 game types, comprising WoP’s unique Spray Your Color Free For All (SYC FFA), Spray Your Color Team Play (SYC TP), Last Pad Standing (LPS), and of course Big Balloon (BB), as well as those old favourites Death Match, Team Death Match, and Tourney. Meet scaled-up and richly detailed maps of everyday places where imaginative characters go berserk with an array of colourful plastic weaponry and power-ups and start rockin’ to the Dieselkopf soundtrack, and the Pad-Anthem performed by Green Sun; so grab those earphones.
