I'm working on a Sven Coop map and this means involving some monsters in action . My scenario begins in a chamber . You are allowed to admire the chamber . If you attempt to go and get some weapons an event is triggered . 3 "vox" words will say "immediate" , "exterminate" , "approach" ( the best I found ) and some texts on the screen telling you that the aliens dispatched 30 robots in order to exterminate you(from an alien "teleporyer"). Your job ? Push the lever , a wall will go up and and you'll be "served" with weapons . The robots spawned are scripted , so they'll come after you . You have an "emergency" button that can be used only once . The button will release 200 snarks from a duct . This snarks will only slow down the robots but won't destroy them , this is your job .
You must destroy at least 20 robots . There is a door that will only open after 20 frags. Before the door will be unlocked a text will appear on the screen if you approach near the door ( "the door is locked , you must kill at least 20 robots to unlock the door" ).
My questions : The game_counter will automatically shut down after 20 (any type) of frags ? .
After 20 frags the game_counter will trigger something to open the door and kill the game_text ( the one saying the door is locked) . How can I do this ? I must mention this : I don't have any experience using the multisource , if the multisource must be involved , so please help me .
