Opcode Arena: The Circuit

Clemens Uhlenhut

About this game

Program robots in an 8-bit firmware language, then test your code in deterministic arena fights.

The Circuit includes the complete Opcode Arena experience and Arena Pack 1:

• GEN-MAZE and GEN-ISLES: procedural arena families generated from each fight seed
• COLISEUM, PINWHEEL, TWIN WALLS, and LABYRINTH: four handcrafted arenas
• Five original training arenas
• Firmware editor and assembler with 28 RF-8 opcodes
• Deterministic simulation: the same code and seed reproduce the same fight
• Challenge codes for sharing, importing, replaying, and answering fights
• ZIP import for moving firmware and saved codes from the free Opcode Arena app

The paid app is a separate installation. Export from Opcode Arena and import the ZIP in The Circuit to bring your work across.

One-time purchase. No ads, subscriptions, in-app purchases, accounts, analytics, or tracking. Works offline.

What’s new

Shield now activates in two ticks and protects against every hit for five world ticks. Challenge Codes made with the previous engine still import and replay under the new rules, with an old-engine warning.
