History Channel: Civil War

Complete the Antietam mission with an accuracy above 95%.

Find all secret documents in the game.

Kill 250 of your enemies.

When you see an ally fighting hand-to-hand with the enemy, help him. Sometimes they will get killed and you could end up alone.

When you finish securing an area, reload your weapon. By doing this you will have a fully loaded weapon in case you are spotted by an enemy.

Reloading a weapon can be a time-consuming process. It pays to plan your reloading time and engage in hand-to-hand combat when facing a greater enemy force. Keep mobile and be aware of your perimeter when engaging.

One of the most important concepts in warfare, the high ground offers you a better vantage point and firing position.

When you are in a stealth mission, stay out of areas with lights and the enemy cannot see you. Note: If you fire a shot they will be able to spot you.

Complete the game on the Hard difficulty setting.
