About CTRL-U: Testing Facility
Become the ultimate android in this fast-paced platform parkour FPS where speed is your greatest weapon. Run, jump, and shoot to dominate time trials and clear every test in the shortest time possible.
Trenton Fluidics has integrated this next-gen tool directly into your robotic arm. Use it to handle any situation: activate circuits, unlock pathways, and take down enemies. Please note: pointing the emitter toward test control equipment or your own optical sensors is highly discouraged.
Enter the Flow state by reaching maximum speed, and maintain it by keeping a smooth and fast movement. This will allow your battery to recharge quickly and drastically reduce the chance to be hit by the enemies.
Push performance to the limit by activating the processor boost to slow down time and sharpen your reflexes. But remember: energy doesn't grow on trees (and Trenton Fluidics hasn't planned any vegetation for the testing environments anyway), so don't waste battery charge.
Push the capabilities of the K-Series prototype to the limit, improve with every run, and clock the fastest times. Only then can the K-Series project be deemed a success.
Trenton Fluidics is the vanguard of robotics and automation—and YOU are the flagship product!
