Graviton Singularity MechaPhysics Missile Mayhem

Game overview

Graviton Singularity Mecha is a top-down arcade defense game where you never shoot a tank to death. You fling orbs of gravity energy that knock tanks around, and the battlefield does the rest: tanks slam into walls, into each other, into the next tank in line, and the crashes cascade.

You pilot one experimental mecha against an endless, clumsy robot army on a barren frontier planet. Every stage is a short, deliberate puzzle of angles and momentum, played at your own pace, with slow motion on tap and a trajectory line that shows where each shot will bounce.

It grows out of the Momentum Missile Mayhem series and Siege Tank Defence, and keeps the moment those games did best: the shot that sends one tank flying into three others.

Controls and interface

You control one mecha from above. It doesn't walk or fly: it creates a gravity pocket and falls into it, so it slides across the battlefield up to a top speed, with a little drift when it stops.

With an orb readied, a trajectory line shows its path through up to four bounces, and how fast it'll be going at each one. The wheels show each weapon's stats and when it's the right tool, so a new player can learn the arsenal while time is stopped.

Game layers

1. 01 · Moment-to-moment

   One stage, a few waves

   

   A wide, walled arena seen from above. Tanks roll in from an open edge in waves of two to ten, never more than about ten at once. You slide out of their firing arcs, read the angles, and launch.

   The best shots rarely go straight at a tank. They go into a wall at an angle and come back into a tank's side, sending it into the wall or into its neighbor. A shield raised at the right moment can even catch a shell meant for the base you're guarding.

2. 02 · Low metagame

   A region campaign

   

   A campaign covers one region of the planet: a map of hotspots where the Legion has landed. You choose where to deploy. A campaign runs to ten stages, each with one to five waves, and the difficulty of each is random: easy, medium and hard in any order, sometimes the same arena several times in a row.

   When every hotspot is clear, a final stage opens, where the Legion's remnants regroup around a boss that appears nowhere else. Every stage is one of four types:

   Stage type	What the tanks do	Your job
   Base defense	Land outside the anti-air fort's range and roll in to shell it	Stop them before they're in range
   Confrontation	Drop into an arena and turn to face you	An all-out brawl, a demolition derby
   Ambush	Flee across the map, or run a convoy through it	Play goalkeeper: let as few through as you can
   Base assault	Pour out of a factory base under artillery cover	Slam its own tanks into the base until it breaks

   The planet

   

   The whole planet is a generator of region campaigns, and each one gets a twist: a different biome (desert, snow, ice, ashen wasteland, barren soil), a shorter or longer run, a hotter or calmer one, a lean toward one stage type, a different set of weapons on hand.

   Because the planet sits on the frontier, the Legion keeps coming back, so there's always another region to clear. The planet map remembers every region you've cleaned up, and after a hundred campaigns it marks the invasion as broken: from then on, it's only stragglers. That's a record of what you did, not a prize.

4. 04 · Practical game flow

   A coffee break or an evening

   

   Launch straight to the planet map, pick up the region you were working on or start a new one, and choose a hotspot. A stage takes a few minutes.

   Stop after any stage and the campaign waits exactly where you left it. Play one stage over coffee or a whole region in an evening; nothing in the game cares which.

Game modes

There's one mode, on purpose: the planet campaign. It already covers every session length, because it's built in nested pieces you can stop between:

The pace is slow and strategic throughout. Waves arrive sooner when you clear them sooner, so a confident player speeds the game up and a careful one never gets rushed, and there's always a short break between waves.

Features and mechanics

1. The heart of it

   Bank shots and the trajectory line

   The mecha's main weapon is a slingshot that makes orbs of gravity energy. Aim with the mouse; how far the pointer is from the mecha decides how hard the orb is flung. A new orb takes a moment to form after each launch.

   An orb bounces off walls, obstacles and tanks until it runs out of momentum or time, then detonates in a last EMP and plasma blast. While you aim, the trajectory line shows its path through up to four bounces and its speed along the way, so you know exactly which hit you're setting up before you take it.

   A shot fired straight at a tank scores one hit and flies off. A shot banked off a wall into a tank's side sends it sideways into the wall, or into the tank next to it. Learning to see those angles is the game.

   

2. Chain reactions

   Knockback is the damage

   

   An orb hitting a tank does little damage by itself, plus a brief EMP stun. What hurts is the impact that follows: the tank thrown into a wall, into another tank, or into a whole line of them. Those collisions cascade, and wrecks and explosions keep pushing their neighbors.

   The Legion makes this easy. Its tanks are heavy, slow and can't steer around each other, and the arenas are laid out so they drive in straight lines, which bunches them together. They even crash into each other by accident. The biggest moments are the ones where one well-placed orb sets off a pile-up across half the arena.

3. Gravity-well propulsion

   Moving by falling

   

   The mecha moves by creating a gravity pocket and falling into it. It slides rather than walks, up to a top speed, which makes keeping your distance and side-stepping a slow shell feel smooth and deliberate.

   The shield holds about five seconds of protection and recharges slowly, so it's for a well-timed tap just before a hit, not for hiding behind. Anchor mode locks the mecha to the ground: nothing can pull or push it, and it fires harder and faster, but it can't dodge, and switching in or out takes two seconds. It's also the answer when your own vortex or shockwave goes off a little too close.

4. Thinking over reflexes

   A slow, honest pace

   

   Every Legion weapon telegraphs before it fires, and its shells are slow and only moderately damaging, so the mecha survives several hits. Nothing kills you without warning.

   Slow motion drops the game to a tenth of its speed for up to ten seconds, recharging slowly, for lining up the shot that matters. The weapon wheels stop time completely while they're open.

   The pace stays in your hands: clear a wave quickly and the next one comes sooner, take your time and it waits, with a short break between waves either way.

5. Everything from the start

   The arsenal

   Nothing is locked, bought or earned. Every weapon is available from the first stage, and powers draw on a reactor charge that refills over time, which is the only limit on how often you use them. Now and then a campaign's twist leaves a few weapons out, so you get to play with a different kit.

   Kind	What's in it
   Orbs	Eight kinds, among them a regular orb, one that speeds up with every bounce, a sticky one that lodges inside a tank and tears it apart, a brute-force orb with huge knockback, a split shot that becomes two on its first bounce, and a singularity orb that drags everything with it without colliding itself
   Cannon	Direct shots: small, medium, EMP and mini-nuke
   Powers	Shockwave, implosion, hack and stun, gravity grip (pick up a tank and throw it), orb grip (catch a flying orb and re-throw it), singularity vortex, drone swarm, airstrike, artillery, antimatter shot, and a nuke that's dangerous up close
   Deployables	Magnet trap, shockwave tower, orb accelerator, and mines (regular and nuclear)
   Turrets	Blaster, beam and drone

   The colony's supply pods sometimes drop temporary boosts: faster orbs, faster energy and repairs, no cooldowns, more ammunition, a stronger shield or quicker movement.

6. Brute force by design

   A clumsy enemy

   

   The Legion fields armored tanks, cars and walkers on treads and wheels, in small, medium and large sizes. Their guns are fixed, turreted (all the way round or only within an arc), or mounted in sets that fire together, like three cannons across the front.

   They drive straight at their target, turning slowly to bring you within a narrow arc before they advance. Each type has a role, a strength and a weakness to learn, the way Doom 2's monsters do: some you must never let close, some you should never stand in front of, some are best used as ammunition against the others.
