Last War Survival Season 6 Guide: Shadow Rainforest, Factions, War Merit and Best Prep

Season 6 is live in Last War: Survival, and it is the single biggest search entry point for the game right now. This season — themed Lost Rainforest and played on the Shadow Rainforest Mega Map — rewrites the rules: the fight is no longer just server-versus-server, it is a faction war between the Deepwood Clan and the Wetland Clan, powered by a fresh War Merit progression system. This guide breaks down the map, the factions, how War Merit works, the new Fungus Institute mechanics, and the best pre-season prep to dominate from day one.

What Is Season 6 — Shadow Rainforest in Last War Survival?

Season 6 unfolds in the Lost Rainforest, where a spreading virus has poisoned the Great River — the shared lifeline of three clans. The jungle is collapsing, creatures are turning into monsters, and the ancient war between the Deepwood Clan and the Wetland Clan has boiled over. You, the Commander, are offered a single choice: join Deepwood or join Wetland. Your faction's final victory decides whether the Shadow Rainforest survives.

The Story and the Map

The season plays out on the Shadow Rainforest Mega Map — a single connected map spanning 8 Warzones and 1 Central Area (the neutral Great River Clan's territory). The layout is 100% mirror-symmetrical: Deepwood holds one side, Wetland the other, and both start from identical positions. For the full narrative and weekly breakdown, the community-maintained Last War Tutorial Season 6 hub is the most comprehensive English resource.

Factions — Deepwood Clan vs Wetland Clan

Season 6 is built around a faction-based war. Before the season begins, each Warzone is assigned to either Deepwood or Wetland, and that alignment is fixed for all 8 weeks. Cooperation, territory control, and collective growth now decide the outcome — not just individual might.

Faction Selection and Faction Technology

During pre-season week 1, the Faction Selection event launches: the Faction Leader chooses which of the two factions their group of four Warzones will join. This choice is permanent for the season, so it shapes every subsequent week.

Three systems drive the entire season loop — Participate → Grow → Strengthen your Faction → Participate again:

The Three Core Systems of Season 6

Beyond the three pillars above, Season 6 also introduces the Faction Award and Season Boost (two items that grant active in-season buffs) during pre-season, plus the Alliance Safe Time setting you should configure before launch. The war itself is settled in the Faction Duel across the 8 weeks, supported by Cross-Warzone Expeditions, Sanctuaries, Altar Conquest, and Outpost battles.

War Merit — Tiers, Daily Stipends and Elite Ranks

War Merit is the headline progression mechanic of Season 6. It is a points-based system that rewards how much you contribute to combat and faction activities. The more you fight, farm, and support your faction, the higher you climb.

How to Earn War Merit Fast

War Merit flows from a wide mix of activities, so even non-combat players stay relevant:

As you accumulate points you rise through Bronze/Iron → Silver → Gold → Platinum → Elite tiers. Each tier unlocks a Daily Stipend — automatic rewards (resources, upgrade materials, special-shop currency) granted every day you hold your rank. Higher tiers pay out dramatically more, so the gap between an Elite and a Bronze player widens fast even with equal playtime. At the Elite level, ranking shifts to a weekly evaluation cycle measured against your peers.

New Mechanics — Fungus Institute, Virus Resistance and Hero Awakening

Season 6 adds new basic resources — Spore, Rainforest Mushroom, and War Merit — plus new buildings: the Fungus Institute, Spore Factory, Protector's Field, and War Merit Shop.

The Fungus Institute is your priority engine: it sets your Virus Resistance, which determines which Zombies and Doom Elites you can beat. You upgrade it with Spore from your Spore Factories. Crucially, your Fungus Institute must reach level 4 before the War Merit Shop unlocks — and the War Merit Shop is one of the season's most valuable assets, letting you buy daily Rainforest Mushrooms and Bait. Push to level 4 first.

Season 6 also debuts Hero Awakening, a new upgrade layer alongside the Exclusive Weapons from prior seasons. The first awakenable heroes are Kimberly (Week 1), DVA (Week 3), and Tesla (Week 5). Invest your hero-cultivation resources here as they unlock.

Best Pre-Season Prep for Season 6

The players who win Season 6 are the ones prepped before the countdown hits zero. Here is the day-one checklist:

Resources, Builders and Daily Freebies

Small daily habits compound: your assigned-clan Visitor brings 10 Bait for Fishing and 200k Rainforest Mushrooms every day — check in to grab it. The Enchanted Fungus base skin (1,500 Glitter Coins from the Glittering Market) grants Hero Attack +5% and a Mushroom Puff that gives a 9×9 grid +250 Virus Resistance for 24h. The Rock the End decoration adds up to +2.5% Golden Fish Chest chance while fishing. Save your speed-ups and diamonds for seasonal building upgrades, the Season Pass, and the Weekly Pass Spore Factory — that is where diamond spending pays off most.

Is Season 6 Worth the Grind — and How to Spend Smart?

Yes — Season 6 is the deepest, most faction-driven season yet, and the War Merit economy rewards consistent activity over raw wallet size. The smart-spend priorities are clear: a Weekly Pass for the extra Spore Factory, a Season Pass for double Season Pass objectives, and diamonds reserved for seasonal buildings and Fungus Institute speed-ups rather than gambled on packs. For the most detailed week-by-week walkthrough, the CPT Hedge Season 6 Ultimate Guide is updated continuously as events unlock.

FAQ

When does Last War Survival Season 6 start?
Season 6 begins with a 2-week pre-season, shown by a new icon below the Duel VS (or Meteorite Iron War) button with a 14-day countdown. After the countdown hits zero, Season 6 events typically start within 10–30 minutes.

What are the two factions in Season 6?
The war is between the Deepwood Clan and the Wetland Clan, with the neutral Great River Clan holding the central area. Your Warzone's faction is chosen during pre-season week 1 and is fixed for all 8 weeks.

How do I earn War Merit in Season 6?
Through PvP battles, Alliance Wars and Raids, killing Doom Elites / Zombies / Doom Walkers, seasonal events and objectives, and exploration or Faction Technology donations. Consistency is what moves you up the tiers.

What is the Fungus Institute and why level it to 4?
The Fungus Institute sets your Virus Resistance, which gates which enemies you can beat. It must reach level 4 to unlock the War Merit Shop, where you can buy daily Rainforest Mushrooms and Bait — a top early priority.

Should I spend diamonds on packs or seasonal upgrades in Season 6?
Prioritize seasonal buildings, the Fungus Institute, the Season Pass, and the Weekly Pass Spore Factory over generic packs. Those upgrades compound your War Merit and Virus Resistance far more efficiently than lottery-style pack openings.
