Practice placing a monkey pirates, selecting it, upgrading to tier 4 or 5 and using the ability then selling it. These skills are transferable to any tower's tier 4 and 5 abilities, but proper skins may be added in the future. Use the R E B I N D button to change your hotkeys. Shoot for a high combo!
