Does IRON NEST have multiplayer or co-op?

Short answer: no — not in the current Heavy Turret Simulator release. The Steam store lists Single-player. The developer FAQ describes version 1.0 as a fully single-player experience.

Now

Single-player

Play on PC via Steam, including the official Demo, which is also marked Single-player / Game demo. This site will not publish a co-op setup guide for a mode that is not in the current product.

Stated as a plan

The same developer FAQ talks about later stages adding multiplayer support for Heavy Turret Simulator, and separately about a co-op project direction. Plans are not features. Re-read the official FAQ when you need a status update.

Official — Store feature list: Single-player (research record 2026-08-14). Developer FAQ thread linked below.

Not treated as official — Third-party “multiplayer module” videos. Community mods are not the Steam feature list. If you use unofficial tools, that is outside this manual.
