Offensive Push is the 4th tier upgrade of the COBRA (Covert Ops Battles Response Agent), an exclusive tower in BTD Battles. It allows the player to send bloons 1 round earlier than normal. For instance, a Z.O.M.G. has to be sent out on Round 22 of BTDB. If you have the Offensive Push upgrade, you can send it on Round 21 for no income reduction. Offensive Push costs $1750.
