I see Frontier, with its two main corridors arranged cross-wise atop each other, its low ceilings nudged by free-falling corpses. I see Frost, with its alcoves occupied by worker droids (whose ceaseless plodding I still occasionally mistake for hostile activity) and its euphoric wall-running routes, whirling you down the flank like a pinball along a rail. I see the bare vertebrae of an Infinite Warfare multiplayer map, a combat centrifuge in which every detail serves to situate and direct, propelling you onward and around as if by magnetism.
