Heart of Evil: Napalm Edition project http://www.moddb.com/mods/heart-of-evil-napalm-editon
I worked on this Half-Life 1 mod quite a while ago now, as a mapper and modeller. It was the first project I worked on as part of a team – I learnt a lot about team work from this project.
Most of the layouts were originally designed by Nathan Ruck, whose layouts I roughly followed when making the maps for this mod (though some maps were entirely my own design). Since the mod is puzzle based I wanted the puzzles to be logical to players, so I spent a lot of time working with beta testers to smooth out the gameplay when redesigning the old map layouts.
