PKEUROs own Blowfish has put up an ARTICLE on our forums stepping through the process of converting QuakeWorld maps to Painkiller. With the lack of good team and duel maps, this process could provide some quick maps if the correct thought process is applied. Due to the obvious differences in jumping distances and other physics, modifications might be required to get the best out of the old maps.
This process has been successfully tested on a number of maps but without the authors “say so” we wont release them. We need to stress the importance of getting the authors agreement before converting any maps. For example, we already have agreement from Slayer to convert any of his maps such as Titan2 and ukcldm2 if anyone wishes to have go at converting these. Get in touch with ME for details if you are interested.
