Line of Defense

About Line of Defense

You control a stationary cannon at the bottom of the screen, defending a line from a column of advancing tanks. Each tank is one of several colours, and your cannon fires shells one at a time. To destroy a tank, the shell colour must exactly match the tank's colour. A mismatched hit or a tank reaching your line ends the game instantly.

The challenge comes from managing your shell colour under pressure: tanks arrive at increasing speed and in unpredictable colour sequences, forcing you to switch colours while tracking multiple threats. When too many tanks are about to break through, you can fire a purple bomb that clears all tanks on screen, but bombs are limited. The game rewards quick recognition and calm prioritisation.

Tips to win

• Memorise the colour-to-key mapping to switch without looking away from the incoming tanks.
• Focus on the tank closest to your line first; ignore further tanks until the immediate threat is handled.
• Save bombs for moments when several tanks of different colours are about to reach the line simultaneously.
