Cyclotronica

Cyclotronica is a single-player game in which you race through experimental reactors and particle accelerators as Mr. Big, an ironically tiny rider on an advanced monowheel cycle. You collect subatomic particles, conduct experiments, dodge and fight antimatter and radioactive isotopes with the S.C.I.E.N.C.E. Gun, solve puzzles and discover elements from the Periodic Table. In the campaign, you control the Mr. Big probe as it carries out nuclear experiments from inside places humans cannot go on their own.

Campaign levels

The campaign has six levels:

• Ionization Accelerator Tunnel
• By Prescription Only
• Pop Nihilism
• Mobile Chernobyl
• The Rent-A-Tron
• A Naked Singularity, A Planck Star

Build accelerator tracks

The Track Builder lets you create and save your own particle accelerator tracks using more than 300 Track Section Prefabs. It includes a Materials Selector and accelerator tunnel parts such as Coils, Curves, Straightaways, Gates, Ramps, Hazards and Particle Emitters. Most Prefabs currently reach about Mark V or VI, and Electron boosts have no speed cap. Track building is single-player; the builder is also intended as a starting point for players to host Cyclotron Races and Crucible Battles.

Discover isotopes

In the Isotope Chamber, you fire subatomic particles and antiparticles at atoms you create to discover isotopes. The chamber includes nearly 3,200 known isotopes, each with a real half-life calculated in real time. You can start with Hydrogen and bombard it with Neutrons to progress through heavier elements, or begin with heavy elements and trigger chain fission reactions. Antiprotons and Antineutrons can break atoms apart or detonate them.

The chamber tracks unique isotopes discovered, atoms manually created, particles and antiparticles emitted, elapsed time, and a top-ten score list. Scores are weighted by isotopes discovered over time, with a smaller contribution from atom and particle spawns.

Atoms and weapons

Atoms awarded through mission interactions are placed in a queue and issued when you complete a level. You can exchange spare particle inventory for additional atoms. The S.C.I.E.N.C.E. Gun interface provides messages and instructions as ammunition becomes available or runs out, and you return to your last-used weapon when you regain enough particles. Weapons have tracers, and Neutron Salvo and Gamma Ray Burst use updated burst behavior. Neutrons also add one to maximum cycle damage, but do not repair damage.

Antimatter has chemical-symbol notation that indicates its approximate hit points and ionization charge, including how many Positrons it may spawn when destroyed. Collisions with Alpha Particles can create deionized Helium-4 atoms after damaging your GyroCycle and removing some of its Electrons.

Campaign changes

The six levels have received changes to hazards, particle systems, bosses, damage and presentation. Completing levels awards Hydrogen in Level 1, Fluorine-19 in Level 2, and Uranium-238 in Level 4. In Level 3, the Antimatter Boss enters through a separate chamber and attacks with dangerous three-round Antiparticle bursts from both sides; you are locked in the boss room after entering. Level 4 implements the isotope system for all its atoms, while its Fission Blast damage radius has been adjusted. Level 5 updates the X-Ray Flash stats, and Level 6 adjusts Gamma Ray Burst.
