This game looks like it was stolen from Epic Games’ designer offices. Instead of a sprawling landscape filled with thousands of feudal soldiers, Quantum Theory is a third-person shooter that has been nicknamed “The Japanese Gears of War” by many who have followed the game’s development and progress. That moniker could turn out to be more accurate than expected if the demo is a good indication of the final product. The game mimics the “roadie run”, the control scheme, the weapon interface, the cover system, the look button and even the soundtrack feels like you’re listening to a Gears tribute band."
