The maximum numbers of certain types of entities that can exist in the FS2_Open engine. Please note that 'Inferno' refers to INF builds, developed to boost engine limits. Starting with FS2_Open 3.6.10 these builds can be used in Multiplayer, older builds are not capable of joining the servers due to several incompatibilities. In addition, Inferno and regular builds are incompatible to each other in Multiplayer; someone using an Inferno build will not be able to play with someone using a regular build and vice versa. Those builds are named after the Inferno mod, but are extensively used by many other projects, like TBP. Inferno builds will become the standard, starting at FS2_Open revision 3.7, with 3.6.12 being the last version to be distributed both in normal and Inferno variants.
