Story: Under certain radiation exposure this artifact opens a portal. Presumably the portal will lead to another artifact in the parallel world. Mission: Enter the portal and find the artifact in the parallel world. You will receive our new development, a suit that will allow you to safely get through the portal, and theoretically protect you from possible dangers in the parallel world. Once you have found the artifact, press this button on your suit and you will get teleported back to the Black Mesa laboratory.
I would have given this a higher score if it was just one level.
Once I got down to the second level, I was driven to madness fighting the boss. Did it REALLY need to follow you at a million miles an hour?
It was just absurd fighting the boss since everytime I died I had to reload a save from the first level and watch a painfully long cut-scene before I got killed again D:
It's probably me just complaining, but I've never gotten so angry at a half-life mod before.
