This map is for Half Life. And I'll name it to "The Protection" because this map was a protection, but now it's broken by some invisible monsters. The story about "The Protection". In 1999, "The Protection" has been made by Doctor Octopus Bean, for protecting the people that has a virus named "Keyos", and this virus is very dangerous that make them to cry, to become a hostile, and to die for themself, and this virus cannot stop, but "The Protection", can stop it. And in the year 2018, "The Protection", is now broken for some reasons: if you touch a trigger, the lights will explode, the fence too, and also the alarm will start, and if you make a barney to unlock a door, the door will explode too! But don't worry, you will never take damage, but if you stay on a door that explodes when a barney unlocks the door, you will take a damage, so be careful here!
