Thermonuclear BerserkerPlanetfall Arcade Blaster

Game overview

Thermonuclear Berserker is a fast, loud, deliberately simple top-down arcade shooter. You fly a nuclear bomb that grew arms, legs and thrusters: a biomechanical war machine launched at an enemy-held world. It falls from deep space through the orbital defenses, down through the sky and across the surface, wrecking everything on the way, until it reaches the world's control nexus and the payload goes off.

A blaster, missiles, a bomb and a berserk slow-motion ability: that's the whole arsenal, with no weapon switching, no inventory and no items. What changes is everything around it. Every launch rolls a different loadout, a different quirk and a different way for each weapon to unload, so no two berserkers fight alike.

It started as a list of everything that bugged Reactorcore about a much-loved little game, Space Chunks 2, and grew from there: Rayforce's dive from space down to a planet's core, Omega Boost's one-way trip from sector to sector, Nova Drift's builds and Gundam Wing's lone machine falling on a world.

Controls and interface

Seen from above, in a wide arena that loops around at its edges. The mouse points the Berserker, which turns toward it at its own turn speed, the way the mechs of Starsector do, and WASD flies it relative to where it's facing.

That's all the keys there will ever be. No upgrade adds a new button or combo; upgrades change what the existing ones do. The HUD shows hull, shield, missile and bomb counts, the berserk meter and a charge bar when a weapon is charging. There's no accuracy rating, no hits-taken grade and no score for how you used your missiles.

Game layers

1. 01 · Moment-to-moment

   One sector, all guns

   

   The Berserker descends into a sector where the enemy is already waiting: a looping arena of warships, turrets, debris and clouds. You drift, boost, strafe and unload until nothing is left, then cruise straight on to the next sector. No waiting for waves to warp in.

2. 02 · Low metagame

   One world, all the way down

   

   A run is a single strike on a single world: the zones in order from deep space to the ground, several sectors each, a boss at the end of every zone, and the nexus at the very bottom. Before each boss you take an upgrade. Clear the nexus and the payload goes off. It's a one-way ticket, and that's the point.

3. 03 · High metagame

   The war log

   

   Canonically it's a small war in a small corner of the galaxy, around Sol and its neighbors, and you can keep fighting it forever. Every world you take goes into the log; every world that held out stays on it, red, waiting for another launch.

   The log itself is the memento. It starts on a red background and turns gradually blue as worlds fall, fully blue at around a hundred, and then generative patterns start growing over it, changing with every world after that. It also keeps a running total of Dominion units destroyed and the tonnage of enemy metal wrecked.

4. 04 · Practical game flow

   Save between zones

   

   After each boss, the transition to the next zone offers a choice: carry on, or save and quit. A whole world fits in an evening, and a zone in a short break.

Game modes

There's one game: launch a Berserker at a world. Each launch runs on two seeds, one for the Berserker's loadout and upgrades and one for the world and its defenders, so any world that held out can be relaunched from the log with the same seeds, to try again until it falls. Each seed also gives its Berserker its own color; launch the same seed twice and you simply get another unit of the same model.

Features and mechanics

1. The heart of it

   A different weapon every launch

   The arsenal is fixed and standard: the blaster, the missiles, the bomb, collisions (armor and shield) and the thruster flame. Every launch starts at the basic level of each, then rolls three to six upgrades already switched on, so you never start naked, and you start differently every time.

   On top of that, each weapon rolls its own double-tap mode, separately for the blaster, the missiles and the bomb. Double-tap its button and it does one of three things:

   Mode	Best for	What happens
   Burst	Hit and run	An instant dump-fire you commit to: triple damage and triple fire rate, then a two-second recovery
   Barrage	Focused firepower	Hold it down and the fire ramps up, every shot stronger, while turning and moving slow to a crawl. The blaster builds heat and needs three seconds to vent if it maxes out; missiles and bombs fire in salvos of at least four, each shot after the fourth half again stronger
   Charge	Prepared multi-kills	A bar fills up. Fire early for up to 60% more damage; wait for full charge and it's a super shot with six times the damage and more speed, blast, pierce, freeze or corrosion, then a one-second cooldown

   Three weapons, three modes each, plus the rolled upgrades and the run's quirk: you'll run out of evenings long before the combinations run out.

   

2. This launch's character

   A quirk per run

   Each launch can also roll a perk, something like a class for just this run. Every one leans toward attack: anything that lowers damage gives something back that still leaves your total firepower higher than before. Waiting and turtling are never the answer.

   Example perk	What it does
   Glass cannon	Double damage, three quarters of the armor
   Bruiser	Heavy armor, heavy guns, slow
   Finesse sniper	Fast, precise, long range
   Spray and pray	Wider spread and more fire rate at 80% damage
   Slammer	Five times the collision damage, and armor hardened against collisions

3. Planetfall

   From deep space to the core

   Every world is taken in the same order, the way Rayforce dives from space toward a planet's heart. The backgrounds change with each zone in simple, clean transitions, so you always feel how far down you've come:

   1. Deep spaceThe guarding fleet
   2. OrbitOrbital defenses that would shoot down any ordinary torpedo
   3. The skyInterceptors and air fleets
   4. The groundBases, factories, depots, defenses
   5. The nexusThe world's control center, and the payload

   Destroy the nexus and every remaining Dominion unit on the world loses its tyrant and dies with it. The design leaves room for more depth later: seas, underwater zones, caverns and the planet's mantle and core, with walls and tighter spaces, plus gas giants, asteroid belts, nebulae and modest megastructures (shipyards, mining fleets, moon bases, prisons, depots), kept at a grounded, low-tech level.

4. Growing on the way down

   Upgrades before the boss

   

   Right before each boss, the Berserker picks up a major upgrade, Metroid-style, so it's there to use in the fight: a new blaster type (freeze, pierce, phase, triple, scatter, ricochet, homing, airburst), a new armor (heat, gravity, reactive, anti-knockback, anti-EMP), a shield effect, a movement trick like a speed charge or a spinning boost attack, or new engine flames.

   Then nine options are offered at random and you take three to five, covering movement, berserk, armor, shields, each weapon, allies and utilities: hijacking enemy mines and missiles, shields that repel shots, a visor that shows what the enemy is about to do or reveals cloaked ships.

   Upgrades have no prerequisites, so the order they come in can be fully random. And they never change what a weapon is: the blaster stays a blaster, never a beam. Homing is an upgrade called seeker that can go on the blaster, the missiles or the bomb.

5. Momentum

   Real drift, real brakes

   

   Space Chunks 2 had no momentum, and its movement felt stiff for it. The Berserker drifts: thrust sets you moving, S brakes, and W and S together bring you to a dead stop. Open space has almost no drag; atmosphere, gas and nebulae add more, so each zone flies a little differently.

   Missiles lock on to the enemy nearest the cursor and, if it dies before they arrive, pick the next nearest. Boosting is on its own key, from a quick tap to a long overboost, so a fast pass through a fleet is always one finger away.

6. No cheap tricks

   Enemies that fight fair

   No invulnerable shields, ever. Nothing turns white and makes you wait for it. Enemy shields are real shields that can be broken.

   Turrets are weak points, not gates. You never have to strip a ship's guns before its hull can be hurt; hitting them just brings the hull down faster, and as a ship takes damage its turrets blow off one by one.

   No ranks. Enemy classes are standard, each with its own weapon, ability, movement and turret slots, and none of them double their stats as the game goes on. Uncommon and rare elites turn up instead, recognizably special. Swarmers, marauders, minelayers, stealth ships, tractor-beam ships, carriers, shield ships, destroyers, dreadnoughts and motherships, with ground turrets and structures you can shoot from above, and bosses built from parts the way Warning Forever builds them.

7. The battlefield fights back

   Space full of things

   

   Space isn't just a few flimsy rocks. Sectors hold big station fragments and asteroids to use as cover, debris fields of small fragments that sting a little and add up if you barrel through too fast, dust and nebula clouds that hide things, and methane clouds you can ignite, which regrow five seconds later. Explosions throw hazardous fragments of their own. The sky and the ground get their own equivalents.

8. Never quite alone

   Wingmen in a box

   

   The Berserker builds its own allies inside itself and releases them like eggs or packages that unfold into small ships linked to it. They fight at its side, and if the Berserker falls, they lose power and crash with it.

   Allies and enemies alike talk: a line when they arrive, when they score a kill, when they're hurt, when they die, and now and then just from confidence or desperation, depending on how their hull is holding up.

9. A hard budget

   Never a slowdown

   Reactorcore crashed an old laptop playing Space Chunks 2, with a stacked ultimate attack and salvos of cluster missiles on screen at once. So the design sets a tight maximum of things that can exist at any moment and keeps the game stable no matter what the player builds.

   It also keeps content cheap: every unit, prop, ally, enemy and boss fits inside a square sprite with a circle collider. That makes them easy to draw, even with generated art, easy to add, and every new one works with everything else.

   Pickups follow the same spirit. Health, missiles and bombs drop the way they do in Metroid, without fleeing candy to chase after or rocks to break open for points, so your attention stays on the fight.
