In 2010 I not only had time to play video games, I had time to find mods for those video games and even to follow mods that were still in development.
This was a “fan logo” I created for a particularly intriguing mod called… “Dual Reality” which was being developed for Half-Life 2.
I don’t remember terribly much about it anymore, but their Mod DB page is still up.
In real reality, “Dual Reality” was actually more of a puzzler / tech demo which allowed players to navigate a fractured multiplicity of realities by way of portals, temporal ghosts, and duplicates.
They didn’t respond to teenage me.
