The training camp holds prisoners of slave race captured by heroes after bloody battles on every floating island. Now the governor has opened the training camp to brave soldiers. You can accumulate fighting experience against slave races by fighting these prisoners.
In the training camp, the challenge is limited by time, so as to accumulate morale by brushing the underworld. When morale is enough, you can challenge BOSS as the main combat mode. Knock down BOSS to get the key to customs clearance. After getting the key, you can go to the next higher training camp to challenge the more advanced robot slave prisoners. The training camp adopts the customs clearance method that many players like, and there are always five levels.
