Phone: left stick to walk, swipe on the right to look, on-screen buttons for the tool, jump and actions.

Everything is made of voxels, and everything breaks. Knock a wall down with a sledgehammer, bring a building down with C4, watch glass shatter, fire spread and debris fly. Take out the supports and the storey fails, and everything above comes down. A city to demolish: suburbs, downtown, industry, harbor, construction site, farm and a mansion. Demolition jobs pay for bringing the target down; heists give you 60 seconds to escape with the loot, straight through the walls. Tools from sledgehammer and chainsaw to nuke, black hole, tornado and orbital laser, plus a tank, a bulldozer and a wrecking-ball crane.
