Breach & Build

A compact first-person training yard for clearing a defender, placing snapped cover, editing a real doorway and practicing shots through openings. Move with WASD, aim with the mouse and fire with left click; right click aims down sights. Press B to toggle building, use the wheel to choose a wall, floor or stepped ramp, and click to place. Press G on a nearby placed wall to preview and confirm a doorway; Backspace resets the edit. X destroys a nearby placed piece; bullets also damage cover. R reloads and 1–3 switch weapons. The solo drill includes one original yard and one active defender. The full 5v5 match, two-story compound, gadget roster and online play are not included.
