Black Mesa Soldiers were aware of the mistake they made. A group of soldiers abandoned the agreement with g-man. The surgeon who survived the abnormal laboratory joined freeman and his team. Physician freeman and his team have launched the unconditional process protocol to get back the border planet xen domination. The short code name is "up". All xen creatures will now be under control. Crystal, the planet will be returned. Another planet wants it. The war must be over now. "Now you have won new enemies and friends, doctor freeman! Give me the crystal. You may be your outfit as your counterpart of your generosity."
