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.

This challenge was a “Test Tube” challenge – a 72-hour weekend challenge with the theme of One Room – the entire map should be set in one room. The challenge received a solid 16 entries, and here they are!

Optimum Fearfor Half-Life
“Three years ago, my newly founded work associates and I started work on a portal experiment that went horribly wrong, due to “unforeseen circumstances”. Between our world and Xen, a horrifically violent alien world, a large rift in the fabric of space and time was formed. This allowed all manner of violent species to come, uninterrupted, through the portal and vanquish the Earth. They caused the apocalypse as we now know it.”

Lunar Descentfor Half-Life 2
“Lunar Descent is an action-adventure game, set on the Xterrier Lunar Colony. It mixes brutal combat, exploration and resource scavenging. To stay alive, players must be careful when dealing with enemies and ever mindful of their limited supplies.”
“It is set in the same universe as Dissolution, but is a totally standalone campaign. There is a heavy emphasis on both setting/location and survival (in the sense that you have to scavenge for supplies in order to survive). Combat is intense and enemies can only be bested if you gather the necessary supplies.
Lunar Descent features a totally new setting for players to explore with a rich backstory to become immersed in; an original soundtrack to complement the atmosphere; and an engaging plot told with the help of various talented voice actors from the community.”
