OTTTD

Lock, load and let the gibs fly in OTTTD, a Tower Defence/RTS game with RPG elements that pits you against some of the weirdest creatures in the multiverse.
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!
 

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!
 
The Story
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.
Is pre-emptively defending Earth ethical? Who cares when the money’s good!MINIMUM:
