Zombie Panic! Source: ZPO
Zombie_Panic!_Source_Level_Creation
First, name your map with the prefix "zpo_". This tells the game which game mode to operate in. In this case, the game will require a trigger to complete the round in favor of either Zombie team or Survivor team.
You will need several ZP:S specific entities to make an objective (zpo) map work properly:
game_win_human game_win_zombie (optional) info_objective_list
You will need to set up an output from the final entity that triggers the end of game, which should look like this:
<output>; game_win_human; end game
It is good practice to use the info_objective_list entity for any descriptive text which will be displayed in the upper left hand corner of the HUD for all players. If you need more customized HUD text, you will have to use game_text.
Please see the tutorial on creating objectives for a basic list of common objective's used in zpo maps.
