When computers go to war it is not noticed by humans. But on a program level there are many things that happen at once. You and three other computers are at war, click on your red squares to build a base that your enemies must navigate through, then build your towers to defeat your enemies units. Hit space bar and then click on what units you wish to spawn and where. When you hit space bar again the battle begins. Your enemy units begin traversing your base, and your units begin attacking theirs. Use all your strategy to defeat all the enemy bases.
