This mod is a standalone port of the Spidertron from RTC2, bringing the massive nuclear-powered walking combat vehicle into its own dedicated mod.
The Spidertron is built for players who have reached the point where normal weapons are no longer enough. It does not spawn naturally, who would have guessed, and is intended as a crafted late-game machine for those who want to turn their nuclear industry into something that walks, fights, jumps, aims, burns fuel, and makes the entire world regret standing in front of it.
Powered by Fission Cells, the Spidertron must be fueled to function. Without power, it shuts down completely, disabling movement, turning, jumping, and weapon systems. With power, it becomes a fully rideable mechanical monster, featuring forward movement, strafing, sprinting, turning, charged jumping, and a custom riding HUD for fuel time, ammunition, loaded rockets, health, jump charge, and targeting.
The machine walks on eight procedural legs that search for terrain, plant their feet, climb uneven ground, recover after jumps, and keep the body hovering above the land below. These legs are not just visual either. They have their own hitboxes and interact with combat logic, while still being protected from the Spidertron's own rockets and targeting systems.
For combat, the Spidertron carries an undercarriage-mounted minigun with spin-up, ammunition tracking, glowing tracer bullets, target-assisted aiming, and heavy mechanical firing sounds. It also has a four-shot guided rocket system capable of locking onto entities or blocks, launching upward before steering toward the target, and falling back to ballistic flight when needed. Its custom rockets include glowing rendering, flame trails, pollution smoke, soft additive particles, custom explosion sounds, and large destructive explosion behavior.
If the guns run dry, the Spidertron can still defend itself with a fallback melee stab using its front legs. Ammunition, fuel, and rockets are handled through a dedicated Spidertron inventory, with gradual mechanical loading sounds so the whole thing feels like a gigantic machine being fed rather than a normal Minecraft mount.
The Spidertron is heavily armored, has high health, and can slowly self-repair while powered, though serious damage may take several in-game days to recover from. It also includes damage warning voice sounds at major health thresholds, a deconstruct option for recovering the machine when needed, and a violent death sequence.
When destroyed, the Spidertron breaks apart into exploded legs and body pieces, mimicking the physical destruction of the mech. If it dies with active fuel or Fission Cells inside, it may leave behind radioactive fallout as one final reminder that you probably should not have built a walking nuclear weapons platform indoors.
