Signal Degradation System
How Static Works: As you move further from other players, your signal weakens. Characters progressively drop out or become garbled, simulating real radio interference.
| Distance | Signal Quality | Effect | Example |
| 0-60% | Clear | Perfect | "Meet at the tower" |
| 60-75% | Good | Minor static | "Meet at t▯e tower" |
| 75-90% | Fair | Heavy static | "M▯▯t at ▯▯e ▯o▯er" |
| 90-100% | Weak | Severe static | "▯▯▯▯ ▯▯ ▯▯▯ ▯▯▯▯▯" |
| 100%+ | None | No signal | (message not received) |
Spoiler: Showcase: Static & Signal
Static appears as characters dropping or garbling when signal quality decreases. Players must move closer or adjust frequencies for clear communication.
