Commander, alien fleets attack in rectangular formations. Read the ship count of the locked fleet, then dial a ROWS × COLUMNS plasma matrix whose area equals it (e.g. 24 = 4×6) and FIRE to obliterate the grid. Purple Divider fleets lock your ROWS — split them into equal groups by dialing the COLUMNS. Fast, correct hits raise the threat level. Don't let a fleet cross your defense line!
Tip: tap the num-pad to dial ROWS/COLUMNS (⇄ swaps) · click any fleet to re-target · keyboard 0–9 type · Tab swap · arrows nudge · SPACE fire
