Four times the fun

"Beat 1 map in 4-player Co-op mode"

- BTD6 description

Four times the fun is an achievement in BTD6 introduced in the Version 11.0 update, along with Co-op mode. It is earned once the player completes a single Co-op game successfully on any diffculty and track in a 4-player game for the first time. The reward for completing Four times the fun is 100.

Summary
Four times the fun is a trivial achievement to get and can be achieved through regular play. The reward is a good amount for the newer players. However, some of those who have a large Monkey Money count won't have much use with the reward.

Tips

 * The player should try finding an Easy - Standard game to quickly finish the Co-op game.
 * The player can try and get 3 other friends so all 4 players can coordinate together easier, making Co-op a way easier time.
