Ok, well something must be going wrong

Here is an arena file that supports all gametypes

{
	map "mp_carentan"
	longname "Carentan, France"
	gametype "dm tdm sd hq ctf"
}

This file would work if your map was called mp_carentan. So change mp_carentan to the name of your .d3dbsp file.

Put this code in a file called mp_mapname.arena, where mapname is the name of your map.

This file needs to go in an 'mp' file inside an iwd.

Make sure your file is a .arena file, not a .arena.txt file. Do this by going into any document folder, then Tools -> folder options -> view, and untick the box for 'hide extensions for known file types'.

They censor your post, as this is meant to be a friendly community. Responding in an angry and violent manner, using swear words, is likely to get you flamed or ignored. You will find you get much better help if you explain the exact problem, show what you have already (eg. post a copy of your arena file, or your map iwd file), and be patient - asking your questions in a more civilized manner.

This is what your .arena file should look like:

{
map  "mp_ge_war_zone"
longname "War Zone"
gametype "dm tdm"
}

Change "War Zone" to whatever your map is called, looks like "German War Zone" maybe?

Place the .arena file in your main/mp folder
