The studio behind the overkill
SMG Studio is a Sydney indie team that turned a pun about tower defense into a cult classic. This is the story of HEROCORP™, the rifts, and why our accountants still flinch at the word "gibs".
Make it excessive. Make it mean something.
SMG Studio was founded on a simple bet: mobile strategy games could have personality, depth and jokes without sacrificing a single point of tactical rigor. OTTTD was our first proper release — originally titled EpicTD, then TDTDTD, until the only honest name left was the most excessive one.
We come from Sydney's indie scene, the same crew behind Death Squared, Super One More Jump and Thumb Drift. Small team, loud ideas, zero tolerance for boring lanes.
Craft over scale
Every tower, boss and one-liner is hand-tuned. We'd rather ship twelve great tower types than forty filler ones — then give them names like the Hottenschitzer anyway.
Depth is the joke
The humor lands because the systems underneath are dead serious: six damage types, real skill trees, armor interactions and a death system with actual stakes.
Players outrank us
Balance patches, new guns, extra battlefields and Stinky Cheese Armour exist because commanders asked for them. The community writes the roadmap.
From napkin sketch to alternate dimensions
The road from EpicTD to OTTTD took whiteboard wars, three name changes and one very committed kraken.
Drag the divider — early lane sketch vs. final battlefield
"We wanted a TD game where the heroes mattered more than the maze."
Most tower defense games make you a disembodied god placing turrets. We wanted mud on the boots — heroes who could die, level, and mouth off. That single decision forced RTS movement into a TD brain, and the whole game bent around it.
The two dimensions, Steamcrust and Nightmare, started as palette tests and ended as full narrative worlds with their own factions, bosses and physics jokes.
- 25 story missions plus endless battlefields
- Post-launch content: new guns, maps and armor
- Ports to PC and Nintendo Switch after mobile
A brief history of overkill
How a Sydney indie studio talked its way from a working title pun to a multi-platform cult favorite.
EpicTD becomes OTTTD
A prototype codenamed EpicTD mutates through TDTDTD before landing on Over The Top Tower Defense — the only name honest enough for the game it became.
HEROCORP™ opens for business
OTTTD hits the App Store and Google Play, lands a 4.5-star average and a Featured slot in Best Games. The flying zombie shark becomes an instant folk hero.
More guns, more gibs
Six new weapons, three new battlefields, an extra endless level, real-time lighting, and the legendary Stinky Cheese Armour. Brass casings start littering battlefields.
Steam and Nintendo Switch
The definitive edition brings high-resolution graphics and crisper audio to PC, then marches onto Switch — preemptive defense goes portable everywhere.
The Australian command post opens
OTTTD Arena launches as the official AU portal: guides, events, services and a direct line to the Sydney team. TPS reports now filed digitally, still in triplicate.
Animation with a psychology degree
Every hero in OTTTD telegraphs personality through movement — the Saboteur slinks, the Assault plants his feet, the Medic checks her watch mid-firefight. We animate the character first and the soldier second.
The same obsession runs through enemies. A motorcycle squid reads instantly at speed; a war tortoise telegraphs its shell phase three full seconds before it locks down. Readability is our favorite special effect.
TARGET PACING
OF HAND-TUNED CYCLES
Silhouette first
Each class reads from across the battlefield — critical when you're micro-managing three heroes against a wave of gunclams.
Recoil honesty
Weapons kick like they mean it. Muzzle flash, brass eject and target flinch all run on the same frame-accurate beat.
Death theatre
The tempa-death™ animation buys you two seconds of grief before the cloning bay invoice arrives.
The palette of a war zone that winks
OTTTD's look pairs military hardware with cartoon confidence — saturated skies, readable silhouettes and explosions you can feel in your fillings.
Color as language
Faction identity lives in the palette: Steamcrust runs cold steel and sea-foam, Nightmare runs ember red on bone. You know who owns a lane before you read its name.
Real-time lighting pass
The definitive builds ship with real-time lighting and shadows — brass casings glint, fog catches beams, and night missions actually feel like fighting in the dark.
- Dynamic shadow maps
- Emissive muzzle flashes
Restrained chaos
Maximum gibs, minimum visual noise. Every effect is tuned so the lane state stays readable even when three towers, two heroes and a boss are all expressing themselves.
- Effects budget per lane
- Priority-rendered boss telegraphs
Two dimensions, one payroll
Rust, tide and claw
A steampunk shoreline where crustaceans evolved industrial union representation. Expect mechanical beasts, dockyard lanes and the Kraken's signature surfacing between your towers.
Lore dossierSuburbia gone wrong
Horror-film streets populated by zombies, floating eyeballs and one very committed airborne shark. The Horror faction resists everything polite.
Survival guideSmall studio, loud output
The team behind Death Squared, Super One More Jump and Thumb Drift — now running the busiest rift in the southern hemisphere.
Community first
Balance requests, fan art and endless-mode rivalries from our Discord feed straight into design meetings.
Proudly Australian
HEROCORP™ may be galactic, but payroll is local. The command post sits at 100 Harris St, Pyrmont — drop by the contacts page.
Partner services
Coaching, clan ops and tournament support run through the Arena services desk — same team, same postcode.
Everyone gets to overkill
Tactical depth shouldn't require perfect reflexes, vision or hearing. We design the chaos so more people can enjoy it.
Readable at speed
High-contrast telegraphs, color-independent lane markers and icon-coded damage types mean the battlefield reads correctly without perfect color vision.
Audio optional
Every audio cue has a visual counterpart — boss roars flash the rim, wave alerts pulse the HUD. You can play a full mission muted and lose nothing.
One-thumb tactical
Pauseable waves, generous touch targets and controller remapping keep the entire campaign reachable for players who need it most.
“The best difficulty setting is the one that respects the player.”

Press corps
PocketGamer called it "wonderfully excessive". Touch Arcade praised the TD/action-RPG meld. JayisGames said it's what mobile tower defense should strive for. We put all of it on the break-room fridge.
