Like explosions? Love giant, flying, undead sharks? Then OTTTD is the game for you for you! Alternatively, if you’d like a strategy game that cleverly blends TD & RTS genres for a tactical challenge across an action-packed campaign then OTTTD will scratch that itch.

We describe OTTTD as “Spaceballs meets Starship Troopers” wrapped in a tasty TD game shell. But anyone under 30 has no idea what Spaceballs is (their loss) so we fall back on “It’s an anything-goes TD game that doesn’t take itself seriously.”

The year is 2136. You work for HEROCORP™, the universe’s 4th largest private military force. Your job is to “preemptively defend” the Earth against alien dimensions. As long as you complete the missions under budget and fill out the TPS reports in triplicate, everything goes smoothly.

Dimensional travel is facilitated by HEROCORP™  rift technology, which is kinda like Stargate but we’re hesitant to throw that in the mix when we’ve already mentioned Starship Troopers.

Is pre-emptively defending Earth ethical? Who cares when the money’s good!


Remember it's OTTTD, which is Over The Top TD. We thought it was funny to smash all the letters together but people keep getting tripped up. It's not OTTD, which is another game altgether. (We're big Transport Tycoon fans though) And no it's not OOTD which we've found out is Outfit Of The Day?! And it's definetly not OTTTTD which is just a silly idea for a game. Over The Top Tractor Tower Defense? Crazy

The Developer

OTTTD the first game from Sydney-based indie studio SMG, who were one of the 10 companies funded by Screen Australia Games Enterprise funding before it was cut.
