Exploring Valley IV: Map Access & Major Mechanics

Players are introduced to Valley IV following the cinematic prologue, quickly immersed in a tutorial on basic exploration, combat, and the factory system alongside Perlica. Full access to the map is only granted after several main quests—until then, most of Valley IV remains shrouded in fog, restricting access to resources outside the Core AIC region.

Key Progression Breakpoints:
– Unlock fog by activating every TP Point (also acts as fast travel/rest nodes and minor XP shrines).
– Advancing past certain barriers requires specific Authority Levels, tied to cumulative progression and side content. Prioritize Authority Point tasks for fastest map reveal.

Not stated in official materials: Exact TP Point and Authority Level thresholds per zone segment.

Power Infrastructure: Relay Towers & Electric Pylons

As soon as you venture beyond the Core AIC, expect to encounter locked gates and disabled machinery requiring power links. The solution is a daisy-chained network of Relay Towers, which channel energy from your base outward. Linking Relay Towers with Electric Pylons is essential for opening new areas, activating mining rigs, and deploying outposts—plan your expansion around reachable power lines to avoid backtracking.

• Advanced Tip: Facilities outside Core AIC require their own power sources. Always prioritize Relay Tower expansion over immediate resource nodes for long-term efficiency.

Resource Optimization: Chests, Ore, Aurylene, and More

Valley IV is packed with hidden chests and rare materials, but not all are equally valuable for early advancement. Here's how to maximize your gains:

• Chests: Contain random drops—prioritize those along main mission routes first for Authority Point boosts.
• Raw Ore/Mining Rigs: Basic ore can be gathered with weapons, but rigs on mineral beds provide a renewable supply. Upgrade rigs as soon as possible—even basic rigs are more efficient than manual harvesting.
• Aurylene: Used for high-level upgrades and crafting; log locations via the interactive map for return visits once challenge areas unlock.
• SOS Robots: Often award event tokens and temporary buffs. Seek them out for side quest completion and unique item unlocks.

Preparation Checklist: Launch Day & Beyond

Make the most of your early hours by focusing on the following:

• Prioritize TP Point discovery for fast travel and healing access.
• Upgrade mining rigs as soon as blueprints/resources allow, streamlining material income.
• Daisy-chain Relay Towers aggressively whenever you expand out of the Core AIC to reduce future backtracking.
• Track Aurylene, SOS, and rare resource nodes using the interactive Valley IV map for return visits.
• Engage with all Authority Point sources (chests, combat, side opt-ins) for swift area unlocks.
