Secondary Fire is an ongoing mapping project of mine. The main goal of this map pack is to bring back that handicapped feeling from the beginning of Portal and Portal 2, where the player only has the ability to shoot one of the two portals. However, unlike the beginning of Portal and Portal 2, the player only has the ability to shoot the orange portal.

What's the difference between orange and blue portals?

Nothing, really. Except maybe what finger does the clicking.

As you progress through the map pack, the chambers will start to get harder, questions may arise, and mysteries will begin to unravel. Use what you've learned through the Secondary Fire Testing Initiative to keep moving forward.


Thank you for taking time to play through these maps, and I do hope you enjoy them as much as I did making them. I'm one person, so development on these maps may take a very long time, but here's hoping they're still enjoyable at the end of the day.
