Pax Autocratica MEC-KONG 7X

Pax autocratica MEC-KONG 7X is Elysia’s last combat gate, not a side boss you farm on day one. The nameplate shows MEC-KONG 7X [Lv.10]. That Lv.10 is the boss label. It is not a requirement that your Leader must be level 10. Winning this fight secures Elysia. The two Decisive Battles before it do not.

Steam never published a health table or a required loadout. This page is one Early Access player clear plus what official patches actually named. An August 2026 first-person recording labeled “first boss fights” reaches the in-game overlord VO (auto-captions hear Mechcom 7X; the live nameplate in written guides is MEC-KONG 7X), then a later line that overlord coordinates have been locked. That streamer still died on the first attempt and asked for more healing potions. Treat the video as proof the gate exists and that an empty kit fails, not as a substitute for the named route. If the client crashes at a first endboss mission — a live Steam thread in late August 2026 — that is a bug, not a missing grenade tech.

If the overlord objective is not on your map yet, use the Elysia walkthrough. This page starts when MEC-KONG is available and the question is whether this expedition is healthy enough to enter.

When to fight, when to Return to Base

The objective unlocking is not the same as the run being ready.

Take the fight when ordinary enemies still die cleanly, the gun in your hands already works on harder rooms, you still have a realistic heal, and you are not walking in already desperate.

Return first when normal fights already force emergency heals, the last rooms before the arena barely survive, the weapon has fallen behind, or you reached the gate mostly because you did not want to leave the map unfinished. Failed expeditions can drop part of the haul. Banking a coherent kit is allowed.

A 2025 Prologue thread told players to heal at a rest planet and dump loot at a logistics planet so a wipe only risked equipped items. Early Access player notes for Elysia emphasize Return to Base. If your live map still has those stop types, use them. Do not import demo-era soldier caps or ship names into this page as current law.

Use the gun that already carried the run

One successful write-up picked up a Laser Rifle shortly before the arena and kept it. After the win, that gun was the first thing credited. That is not a studio rule that Laser Rifle is required. It is evidence that abandoning a working kit at the door is a worse idea than a prettier rarity.

Do not swap because the new gun sounds exciting, because you assume the boss wants a specific name, or because you want to rebuild cores five minutes out. Fragment rules and sourced names sit on core fragments and best weapons. For this fight, the only loadout question is: does this setup already clear the road?

Second Chance, State-Issued is armor-shop insurance unlocked after the first Decisive Battle in player notes. Useful. Not a requirement. The successful attempt still came down to damage, heals, and grenades.

Gatling pressure is the real puzzle

MEC-KONG enters with a huge Gatling gun. Sustained fire is what turns a manageable attempt into a panic attempt. The player who cleared it did not describe a complicated phase chart. The rhythm was: deal damage while the exchange is favorable → break when the stream is bad → recover or reposition → start the next exchange from a safer place.

Do not treat every second as a damage race. If the gun is already pouring into you, proving you can keep shooting for one more second is how the margin dies.

Heal before the next burst can end the run. The same successful attempt dropped to Critical Health: 4/314 HP. The author survived and still told readers not to copy that timing. Against trash you can finish a target before drinking. Against MEC-KONG there is no later Elysia fight that makes holding the heal smarter.

Grenades are for this arena. The same write-up had been hoarding them, then spent them, and saw the boss stop shooting briefly after a grenade landed. That is one observed window, not a published stagger table. Use the window to heal, move, or push. Do not get the opening and then stand in the same panicked trade.

Steam’s August 2026 “first boss fights” footage is full of tanks, legs, cannons, and attempted captures on large machines. Capture still uses F and Capture Rate. Do not turn the overlord into a capture tutorial unless the live prompt says the target is legal and the run can afford it. Advanced rounds from AG-14 exist for elites and bosses; they are still not a reason to wipe the expedition to pocket a robot. See prisoners.

After Boss Victory

Defeating MEC-KONG 7X completes Elysia’s unification. Return. The next sector is harder. Research Soldier Training Center, spend surplus soldiers into a core squad, and fix food, hours, and haul you ignored on the last push.

A pax autocratica MEC-KONG 7X page that printed an HP table or “best core for monkey” would rot in a week. AG-14 already moved Vortex Shell and Thunderbolt Arrow numbers. The honest kit is the one that already survived the road, plus respect for Gatling, plus heals and grenades spent in this fight instead of saved for a fight that does not exist after it.
