Nowel's Shattered Planet Escape Portal

An alternative ending for Space Age. Reaching the Shattered Planet is no longer the end of the story: it is where you find the way home.

Among the ruins lies a Dimensional Relic. Bring it back to Nauvis, research the technology it teaches you, build an escape portal — then survive long enough to walk through it.

How it works

1. Recover the relic. Send a platform to the Shattered Planet. The relic is loaded into its hub. It weighs a full tonne, so bringing it down to Nauvis is a dedicated trip. Lose the ship and you can simply go back for another.

2. Research the portal. The relic unlocks a technology costing 300 of every science pack in the game — the last research of your playthrough.

3. Build it in four phases. A 9x9 structure that grows in stages, each with its own artwork and its own materials: excavation with cliff explosives (and the stone must be carried away by inserters), foundations, structure, systems. The hardest product of every planet is required. Beacons and speed modules work on the construction site, so accelerating the build is a logistics decision.

4. Charge it. The finished portal draws up to 2.4 GW and needs 19 440 GJ — around two hours and fifteen minutes at full power. This is when the planet turns on you: attacks cost far less pollution, groups form in seconds, nests expand aggressively, and every biter and spitter is replaced by an empowered variant with more health, damage, speed and resistance. Until this moment the game is completely normal.

5. Survive the activation. When the charge completes, every biter in the region turns toward the portal at once and a 20-minute countdown begins under massive assault, with lightning striking the ring.

6. Escape. Walk into the open portal.

Lose the portal and it detonates like a nuclear weapon. The survivors settle the region, and you will need another relic to try again.

Factorio 2.0 and the Space Age expansion.

Notes
Localised in English and Catalan.
Around 30 settings to tune difficulty, performance and pacing. /psp-preset applies a set of values suited to a large late-game base in one go.
/psp-debug and /psp-load report exactly what the assault system is doing, including where its biters are and whether the pathfinder is saturated. /psp-panic is an emergency brake that clears the mod's units instantly.
Enemy strength (health, damage, speed, resistances) lives in the Startup settings tab and needs a restart to take effect.
While the portal is active the mod modifies map settings (attack cost, group formation, enemy expansion) and restores them afterwards, so it may conflict with other mods that manage enemy behaviour.
This is an early release, tuned mainly against a large late-game base. Bug reports very welcome.
