Guide: first steps in survival
- Watch your Sanity. Dirty food and water lower Sanity and max health — cook clean supplies.
- Base near resources. Build by water and forest: wood and clean water are the foundation of crafting.
- Upgrade memetics. The memetics ability system unlocks workbenches and ultimates — pick a branch for your style.
- Study the mutants. Every boss has weaknesses: prepared weapons and grenades decide half the fights.
- Play the season. Seasonal servers give unique rewards and fresh mechanics.
Tips
- Redeem codes before creating a second character — some rewards are account-bound.
- Do not carry your best loot without need: dying in contested zones costs a lot.
- Build away from roads — raiders follow them first.
- Watch for Twitch Drops: watching streams grants rewards without codes.
- Join a clan: shared bases outlast solo fortifications.
