Game description

OTTTD stands for Over The Top Tower Defence, and you'll see why when you're blasting 9 kinds of hell out of a Cactus Ghost that's making a beeline for your battlefield HQ. You play as a commander for HEROCORP™, the 4th largest private military organization in the galaxy. A long period of peace has left the company coffers a little bare so the science division developed Trans-Dimensional Rifts, opening up lucrative opportunities for war in other universes. It's like Starship Troopers meets Stargate meets Spaceballs, with way more explosions!

Key Features:

  • Ridiculously definitive edition:

    Prepare your eyes and ears for incredible deluxe-ness! Featuring crisper sound and high resolution graphics, the PC release of OTTTD will leave you feeling like you've actually stepped into an alternate universe and started blasting everything to smithereens.

  • Deep RPG Mechanics

    OTTTD lets you choose from 7 hero classes to make up your squad of 3 battlefield employees. The more action they see the more XP they earn, giving you the chance to level them up through custom skill trees, including powerful combat abilities to unleash during the fight.

    30+ active abilities

    40+ passive skills

    30+ equippable weapons

    multiple armor options with stats to suit your play-style

  • Weapons! Weapons! WEAPONS!

    With 12 tower types to build and 6 different firearm classes, HEROCORP™ has got the hardware to ensure you can wreak havoc in your own personal style.

  • Disgustingly varied foes

    The range of enemies in OTTTD is wide enough to soothe even the itchiest trigger finger. Floating eyeballs? Check. Gunclams? You know it. Giant armored Wartoises? Of course. You'll even go toe to fin with a giant flying shark, and show the mythological Kraken who's boss!

Over the Top


They weren't exaggerating when they said "Over The Top" with this game. Usually, the tower-defense game is played in an almost passive manner: laying out your units, watching the units walk through predetermined paths, upgrading units—lather, rinse, repeat. This game subverts that comfort and thrusts you into combat, giving you an active role in the defense of your tower. With crazy missions and hours of endless fun, any so-called fan of the genre should not go about their lives without first checking this out. For those new to the genre, then prepare for the mayhem!

New strategy game.


That's very cool strategy. It has a lot of effects and shooting and everything you could wish a strategy game to have. The graphics aren't that good, but for a strategy game the gameplay compensate the bad graphics. You can build machines which will shoot all the enemies that approach your empire to try destroy it. It's separated on waves. With each passed wave it becomes harder and harder, there are a lot of weapons which you can use to stop the enemies. Go pick that amazing strategy game.
