About 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!

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!

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!

Exactly what it says on the tin: Over The Top Tower Defense. It takes standard tower defense lanes and forces you to micromanage three hero units at the same time, dodging boss AOE attacks while upgrading your turrets. The battlefield gets hilariously messy with meat splatters and ragdolls everywhere. It grinds to a bit of a repetitive halt late-game when enemy health bars skyrocket, but the core loop is incredibly fun.

I installed OTTTD for a quick tower defense session. A big mistake on my end. Now I’m emotionally invested in defending Earth from aliens, robots, monsters, and what I’m pretty sure was a cosmic squid at some point. The art style is amazing ,it looks like a Saturday morning cartoon that accidentally wandered into a war zone. And yes… there is grind. But it’s the dangerous kind of grind where you say: "One more mission so I can unlock that upgrade".…and suddenly it’s three hours later and you’re researching weapons lnstead of going to bed on time. Highly recommended if you enjoy tower defense, strategy, and losing track of time.

OTTTD is a loud, energetic, and deliberately excessive take on the tower defense genre developed and published by SMG Studio, and it fully commits to its subtitle, “Over The Top Tower Defence,” in both tone and mechanics. Rather than offering a slow, purely strategic experience built around passive observation, the game injects constant activity, humor, and RPG-style progression into every mission. From the outset, it establishes itself as a playful and chaotic alternative to more traditional tower defense games, aiming to keep the player actively involved rather than simply watching carefully laid plans unfold. The premise revolves around a hyper-militarized organization tasked with eliminating interdimensional threats before they become a problem, and this absurd setup sets the stage for the game’s irreverent attitude. Missions take place across stylized battlefields where waves of bizarre enemies flood in from portals, and success depends on a balance of tower placement, resource management, and hero micromanagement. Towers can only be placed on fixed pads scattered throughout the map, which turns each level into a spatial puzzle where choosing the right combination of defenses…

Although I love SMG Studio and enjoy [b] Over The Top Tower Defense [/b] for its funny enemies (like the flying Shark Boss, which is probably a distant relative of Bombardiro Crocodilo) I cannot recommend this game, especially for a 100% completion playthrough. The grind required to finish the game and unlock the "CEO of Blowing Stuff Up" achievement is tedious. To earn it, you have to replay the same stage over and over to gain XP. Starting around level 50 I had to repeat "Mid Boss Airfield" mission roughly 400 times and spent more than six hours on the boring repetitive actions while watching my favorite letsplayer play through [i] Lies of P [/i] on YouTube. 6/10
