What is StalSide?
A survival game where you're trapped inside a simulated post-apocalyptic world that "actively hinders intruders". The Steam page lists:
- Procedural exploration: wild zones, random loot and spawns, so no two expeditions are the same.
- Co-op for up to 8: share resources and cover each other's backs.
- Survival: scavenge to craft weapons, tools and shelter; face wild animals, hostile humans and unknown creatures, plus deadly weather and anomalies.
- Light progression: a minimal levelling system and a simple "set it and forget it" farming system.
- Customisation: anime-inspired characters with lots of clothing.
What's planned for StalSide's Early Access?
The developer expects one to two years in Early Access and plans deeper character customization, a vehicle system, new weapon animations, better NPCs and character progression such as skill trees and a basement. The game is playable now but "core mechanics are not balanced", the FAQ says. There's no plan to raise the price after Early Access.
Is there a StalSide demo?
Yes, a free demo is on Steam.
Is there a StalSide trailer?
The official trailer plays on the StalSide Steam page.
