Your builds are no longer just creations — they’re targets. Keen Software House has officially launched Hostile Encounters, the game-changing Alpha update for Space Engineers 2 that introduces combat NPCs to the sandbox for the very first time. From today, the Almagest System isn’t empty anymore — and the enemies you’ll face are just as capable of navigating, fighting, and destroying as you are.
Meet the Threat — Renegades & Boatmen
Two hostile factions have emerged across the system, and they don’t just stand around waiting to be shot:
- Renegades — Scavengers and pirates patrolling stations, outposts, and wreckage. They patrol routes, take cover when fired upon, react to damage, and call for backup. They’ll hunt you inside your ships and stations as easily as they do in open space
- Boatmen — Heavier, tougher leaders of Renegade squads. Slower, more heavily armoured, and deadlier — these are the lieutenants you’ll want to spot before they spot you
Crucially: they move through the same fully destructible world you do. Walls, corridors, hull sections — nothing is safe. If you build it, they can enter it, damage it, and bring it down. Your defences matter more than ever.
More Than Enemies — The Full Hostile Encounters Changelog
NPCs are the headline feature, but the update reshapes the entire experience:
| Category | What’s New |
|---|---|
| Combat NPCs | Renegades & Boatmen with patrol, cover, and communication behaviours |
| Almagest System | Expanded locations, new contracts, overhauled ore distribution, improved lighting |
| Environment | Verdure flora system bringing richer vegetation to planetary surfaces |
| Building Blocks | Cables, Pipes, Armour Slabs, Interior Turrets, and decorative props |
| Combat FX | New impact, explosion, and damage visual effects |
| Performance | Optimisations across the VRAGE3 engine |
“We originally announced Combat NPCs and Co-op Multiplayer as part of the same update. During development, the NPC systems reached a point where they were ready to go into players’ hands sooner. Rather than hold them back, we decided to release Combat NPCs early.”
— Keen Software House
Four-player co-op multiplayer remains in active development and is targeted for an early 2027 release.
Design Changes — Building for Defence
This update fundamentally changes how you build. No longer just about aesthetics or function — every corridor, door, and turret placement now matters:
- Internal Layouts — Chokepoints, defensible perimeters, and fallback routes are survival necessities
- Interior Turrets — Newly added automated defence systems to patrol your decks when you’re away
- Resource Risks — Renegades will contest mining sites and salvage runs; high-value ore locations now carry real danger
- Contracts — New missions explicitly task players with clearing Renegade-held facilities and retrieving stolen cargo
Status & Availability
- Platform: Steam Playable Alpha
- Update Released: 19 October 2026

Your Creations, Under Attack
Space Engineers has always been about freedom — build anything, go anywhere. Now, for the first time, you must also defend what you’ve built. Hostile Encounters doesn’t just add enemies — it gives your universe teeth, and turns your engineering skill into your best survival tool.
Update your game, reinforce your bulkheads, and watch your back. The Almagest System has visitors — and they’re not here to negotiate.
