RPMegaRaider
Explore and survive a massive 800x600 scrolling tile data vault
Mission Overview & Story
Escape the data vault in this sprawling retro action-platformer built for RP6502. You play as a raider dropped into a giant scrolling maze packed with hostile security drones, energy pickups, and one very expensive Terminus reward. Grab points, survive the swarm, and step through the exit portal when you decide the run is done!
Vault Engine & Technical Features
- 800×600 Tile World: Crisp 320×240 pixel art with smooth camera scrolling across a massive multi-screen complex.
- Dual Layer Tile Streaming: Foreground collision geometry and background parallax layers streamed directly from ROM using ring-buffered memory commits.
- Dynamic Hazard System: Shield collision mechanics, drone respawns, and escalating hazard pressure.
- Arcade Audio: Custom OPL music and pulse-pounding sound effects tuned for arcade pacing.
Objective & Victory Conditions
Explore and score as much as possible. There is no mandatory shard quota — exit through the portal to end the run on your own terms. A perfect-score run totals 300,000 points!
