Anyway, this mission have a special tower like the Wizard Lord mission, it's the Railgun and it'll be the ONLY tower you'll ever have! The Railgun is like a Dartling Gun that shoots 3 darts at once (it's like 3 Dartling Guns crumped together into one) but it can be upgraded to 4/4 and each upgrade only cost twice as expensive as its responsive upgrade for the Dartling Gun (seeing how it's 3 times stronger...). For the Ray of Doom upgrade, it won't shoot 3 Ray of Dooms, instead it'll shoot a blue Ray of Apocalypse that have the good old infinite pierce and can pop bloons thrice as fast! If the Railgun is upgrade to 4/4, it'll shoot that deadly beam AND shoot 9 Hydra Missiles at once (ack!) AND have that ability that will kill 300 bloons instead of 100! This mission is a 50-round mission at
