20 10 has three different teams, one is the Poseidon team of navy seals, four members are the mother, voodoo, priest and rabbit played by the players, the second is the Wolves of Delta, which is a sniper team, and the four members are Panthers, Vegas and Gray People.

The warrior takes the Grey Whale Sharks as the protagonist, and the player will play the stump of the Grey Whale Sharks. The teammate is still the familiar "mother". After the hostages are rescued, the two will be led by Voodoo of the former Poseidon team. After this campaign, the "priest" played by the player resigned without authorization. Later, after the priest was injured by a train explosion when he visited his wife and daughter, he learned from his mother that his wife and daughter had missed the train and were irrelevant. At his request, he joined the Blackbird Task Force led by the "Grey Man".

I won't introduce the detailed story. If you have any questions, just ask.
