Around November of 2011, Grymmoire and I set out to write a guide/article/essay on monster placement in Doom maps. This was partly to help newer modders, and partly as an exercise in learning more about design themselves. We asked several award-winning map designers for opinions and checked a few classic and award-winning maps. Here, finished in mid-2015, is the result. This is aimed primarily at the Doom community and uses examples from Doom exclusively (some from popular level-sets), but the information could also help placement and design in other shooters.
Monster placement is arguably the most important feature of any map. It contributes a great deal to difficulty and enjoyment. Unfortunately, it’s also one of the components that can be difficult to get right for newer mappers. Thus, to help out as much as we can, we’ve asked a few famous, well-respected mappers their opinions and strategies with regards to placing monsters on maps, and we’ve written this to condense a lot of it into an easy-to-understand package for new mappers to benefit from.
