SURVIVAL_CODE A simulation runs for reasons it won't explain. You are the construct inside it, fighting wave after wave of malware with no briefing, no goal, no promised ending — just the growing certainty that survival is the only path to the truth. SURVIVE Auto-firing Functions by default, freeing you to focus on movement and trigger timing. 8 distinct constructs, each with its own energy-gated trigger and playstyle - reflect projectiles, double your output, clear the screen with a shockwave. 8 malware threats, each with a readable tell - charging tanks, segmented worms, projectile-spraying viruses. Survive 20 escalating waves, from a lone probe to a screen flooded with hundreds of threats. Time-based survival - outlast the clock, don't chase a kill count. UPGRADE A node-based upgrade system where the upgrade screen is a circuit board - drop signal nodes on a grid and wire them by color to route stats into your build. Two separate grids: one reshapes your Construct, one reshapes your Function, so character and weapon evolve independently. Spend Code Parts in the shop between waves: buy nodes and modifier chips, lock what you want, reroll what you don't. Wire it right. Survive to victory.
