The Infobox for Maps is a simple way of summarizing information on a map.

Syntax

{{Infobox Map
| name = Dude's cool map
| author = Dude
| image = dudes_cool_map.jpg
| image_caption = Look at Dude's cool map!
| game = List the games the map is available for.
| link = [http://link.to/dudes/cool.map]
| ffa = yes
| team = yes
| holocron = yes
| jedimaster = yes
| duel = no
| powerduel = no
| ctf = no
| cty = no
| siege = no
| additional_gametypes =
* [[UberMod|UberMod MegaSlaughter]]
* [[UberMod|UberMod UberGib]]
}}

Only the name parameter is mandatory but if that's your only one you probably don't want an Infobox, just a heading.
Only gametypes set to yes are listed.
Use additional_gametypes for custom gametypes.
The link parameter is not post-processed to allow for multiple links.
