Attacks

You can strike other empires in several ways.

Regular Attack

A direct assault with your army. Your attack strength is compared to the enemy's defense. If you win, you capture some of their regions and take some gold. Your bombers first destroy the enemy jets that are on the ground.

Nuclear Attack

Turns some of the enemy's regions into waste. It costs a lot, and the cost grows with the size of the target. Large numbers of enemy turrets can shoot down some of the missiles.

Chemical Attack

Kills many of the enemy's people and troopers, but harms fewer regions. Enemy tanks help defend against it.

Biological Attack

Harms the enemy's people and troopers, but not their land.

Doomer Kaboomer

The ultimate weapon, aimed at a whole enemy planet rather than one empire. The whole board funds it, and only one can exist at a time. It takes a few days to build, then strikes every empire on the target planet. Defenders can send jets to shoot it down before it finishes.

SDI Program

A shield you fund. When it is complete, it destroys about half of the missiles fired at you and cuts attacking jets' strength by about a quarter. Technology regions lower its upkeep.
