KSRe adds a wide variety of both new mechanics and stock changes, often inspired by reality and suited to players of all experience levels. Campaign progression has been completely redesigned to fit the added layer of real-world aerospace challenges, starting with an equivalent of the first human rocket program (Opel-RAK rocket vehicles and planes). Several new gameplay systems provide a more comprehensive space simulation, including life sciences and social sciences.
Propellants: cryogenic, hypergolic, ignition failure, ullage, throttle limits
Engineering: single-fuel containers with fuel switch & simple fuel ratios
Kerbal Life: life simulation, kerbal health & damage, social simulation
Rocket Science: new science sources, specialization, tech prerequisites
Damage: part damage, deterioration, part faults, PAL 5000 diagnostics
Progression: new tech tree & missions, facility levels, tech discovery
Resources: ISRU for fuel production, resource conversion & life support
Recommended: Install KSP2 Redux and extract the latest version of the mod to the Redux install directory
Legacy support only is provided for the non-redux base game using the oldest v0.31 download
Exploration mode: (recommended) starting a new game is necessary due to the total campaign overhaul, and includes an integrated progressive tutorial.
Sandbox mode: Existing saves are compatible if all vessels are recovered.
