The name Futuremark should be one that most people who like tinkering with their PCs should know quite a lot about. They make 3D Mark, perhaps the most famous benchmarking tool for the PC to date.
What most people don’t know is that Futuremark also make games; their first was a PC first-person shooter called Shattered Horizon, which looked fantastic but was deeply flawed at launch. Then they made Hungribles for the iOS, which was a little more successful, and is supposedly quite fun. Now they have returned to Steam with the Unstoppable Gorg, a new and different take on the good old tower defense genre.
