I believe you've got it seraph. The map cannot be just an arena for combat - it also has to have areas that are more valuable than others, so players won't always take the shortest path to their enemies - or will take the shortest path and have to fight an uphill battle. Also, two types of missiles maybe? I know almost nothing about the Metroid series, though, so disregard that if necessary. Thanks for the great mod, seraph & team!
