SDX2 is a complete remake of the Expanse experience from the ground up. While the theme, feel, and a lot of the core concepts are the same as SDX1, a lot has also changed.

Here’s a list of some of the major differences.

Mechanics

• No more fast/slow zones - you can go up to 50km/s anywhere. Speed is only limited when in potential combat or collision scenarios.

• A new solar system map 5-10x larger than SDX1, with every planet, all major moons/asteroids, and a real sun at the centre

• New mission system - pick up contracts from stations to earn tech and reputation with NPC factions

• A reimagined Nation system (coming soon)

• A wide range of new NPCs and PVE combat encounters

Building

• Block limits are now handled via a Ship Core system - you can spec your ship into a particular role (Corvette, Frigate, Hauler, etc.) for tailored limits

  • Drive limits are determined by your core, rather than maximum signal

• Revamped tech progression - multiple tiers of tech, multiple tiers of most blocks

  • Different tiers of tech are being gradually unlocked as we roll out features

• Over 500 new and redesigned blocks - weapons, drives, sensors, production, cosmetics, and more.

Combat

• Overhauled weapon systems

  • Railguns now punch through entire ships

  • Torpedoes have been split into multiple roles

  • Increased specialisations of different PDCs

• Variable maximum speeds based on your class of ship

• A new Signals and Detection system, giving you better control over how you detect other ships through various blocks (Sensors, Lidar, Radar, etc.)

• Thruster and reactor output now degrades as the blocks take damage

• All ships now use Water as propellant - no more exploding hydrogen tanks or fuel can extractors
