Here's my ideas of some BTDB Special Missions. Note that this is not for the mobile version, but for the flash version on the NK website. Mobile version pack coming soon. What makes difference between other special missions for BTD5 is simply the fact that two players are playing against eachother during the mission. But how can you find an opponent to start the mission? Well, just like how you usually play assault/defense mode, there's a new button that opens a special mission menu. You can then select a mission you want to play, then wait to get matched up with another player that coincidentally wants to do the same mission! Alternatively, you can play exclusive missions with your friends. But however, only one player will complete the mission and claim the reward by beating the opponent
