This post explains general steps to make a simple playable Counter Strike fightyard map. You can learn the details at Superjer
Put cstrike in your Counter Strike 1.6 or Condition Zero installation folder.
Valve Hammer Editor or QuarK (Quake Army Knife)
info_player_start (CT Spawn)
info_player_deathmatch (T Spawn)
light (self explanatory)
info_map_parameters (buy setting)
armoury_entity (weapon spawn)
Choose “Neither CT’s nor T’s can buy guns” in Weapon Buying options, so neither player teams can buy any guns.
Fill “item” with desired weapons (mp5, m4a1, etc)
Happy Mapping! 😀
