Castle Crusade

This game has a simple principle and very good playability. Increase mining operations and produce combat units, or you can construct defenses. You have only one miner, take good care of him. Gather bonus resources across the map. You may construct siege machine to help you with enemy installations. Later you can manage a train base, where is possible to train new troops and upgrade old units. Speed is critical to get higher reward. You can buy upgrades for gathered gold. 10 full missions await you and you can get stuck at fourth map, where you first can produce archers. This game offers excellent design and some battles may last over an hour.
