GRENADE LANECamera: drag = look · right-drag (or shift-drag) = slide · wheel or W/A/S/D = move, E/Z = up/down, Shift = fast · presets below, R / double-click = back behind the line.
Launch: hold SPACE or the THROW button (cooks the fuse), release to throw from where the camera is, along the crosshair. Q = underhand lob, F = roll. 1-7 pick the explosive. Touch: drag to look, two fingers slide / pinch to move, hold the buttons. V = replay camera.
Demolition: press the Demolition button, pick a level 1-11. Every structure is built of real cells: a blast breaks what it throws fastest, whatever has no support (or whose weight is off its footing) comes down as one piece, and pieces that land hard break up. P = stick a primer (goes off when a blast or falling debris reaches it) on whatever the crosshair points at, T = retry.
