MW4 DMZ solo boss run: how to kill Iskra at Cheonwang Peak Array, from kojiro51's 10-minute loot route

Watch his video first

kojiro51 made this run, and his video is the primary source: the drive, the building and the fight are all on screen in his six minutes and twenty-two seconds. It is in Japanese, and YouTube can translate the captions. Use this page as the companion to it. If you plan to copy the method, watch the chapter you need first, and subscribe to his channel if it helps you. He also streams on weekends.

One boss, one building

The video follows one boss: Iskra, a Lieutenant, in one building at Cheonwang Peak Array. It is a solo loot run built around her. kojiro51 does not cover the other Lieutenants or the Commanders, so we have not written a solo method for them and we will not guess one. When we find a sourced method for another boss, we will add it here with its source. Our bosses page keeps the full roster, and our solo lieutenant hunt guide covers a different run by another creator.

Where Iskra is: Cheonwang Peak Array

He puts the run at Peak Array, in the middle of the map. On our Hajin map that is Cheonwang Peak Array, the largest telecom array in Hajin, on a flat summit near the centre, and our map data rates it Medium. In the video he enters one building with at least four floors: server rooms on the second and fourth, and a key room, a safe and Iskra on the fourth. He says you can go in from any side and shows the door he prefers on screen. We have not placed that door or that building, so pin 1 marks the array as an area, not a building. The array pin comes from Activision's own marker on the map; the name of the place comes from his Japanese captions.

Step 1: buy the intel before you deploy

Before deploying he pays 25,000 for boss intel, and he says that is what makes her spawn. He builds the whole run on it: his plan assumes you are going to kill her. We take this to be the Boss Board purchase described on our bosses page, a station in your FOB that unlocks after your second DMZ Order and sells Lieutenant intel. Two descriptions, two claims. Our bosses page says a Lieutenant can be active whether or not you are tracking her, and describes intel as a way to find her. kojiro51 says the purchase makes her spawn. We have not tested what the intel changes, so we show both.

Step 2: get there first

Once the match starts he takes the nearest vehicle and drives to Peak Array flat out. His rule: speed is life when looting, so get there before anyone else. He says you can enter from any side and picks the door nearest the objective, which he shows on screen. If you follow him, watch that part of the video for the door.

Step 3: climb to the fourth floor and kill Iskra

Iskra is on the fourth floor once you are inside. He tells you to ignore all the trappers (his word) and climb as fast as you can. If there are bots on the way, he reloads after he drops them, so that he meets Iskra with full ammo. Then headshots, every shot. He says that takes her down in one magazine, and if you are worried he suggests an extended magazine for more rounds. When she falls the traps disappear. Clear the bots around you before you start looting. One magazine is his result with his weapon, which his captions do not name. Our bosses page notes that Lieutenants are more durable than ordinary enemies, so treat his count as a good day, not a promise.

A solo setup, from kojiro51

His captions do not name a weapon, so we do not either. What he asks for: An extended magazine on your main gun, for the Iskra fight. Full ammo before you meet her: reload after every group of bots on the way up. The nearest vehicle for the drive in. Lowered graphics settings, for faster looting (next section). The random skill that shows the final exfil point, if you have rolled it. Treat this as his setup, not a tested loadout. If you find the key, IceManIsaac's tips guide covers secure slots, which protect an item if you die, so a failed run does not cost you the key.

Looting faster and leaving quietly

Faster looting. He says that if you lower the resolution in the display settings, the parts of the scene you can interact with, such as the server racks, turn white against everything else, so you can see what is lootable at a glance. Our graphics guide covers visibility settings, and we have not tested his tip. Leaving. Speed matters again here: if you linger, other players show up, so go as soon as you are done. He also says a random skill can reveal the final exfil point, and that with it equipped you can see that point from the start of the match and actually use it, so you extract from a point other players cannot see. We have not tested that either. Wing Mait note: the risk he describes, other operators arriving while you are busy looting, is the one our operator contact callouts are meant for. They are in development: a solid red diamond on the minimap is an enemy operator and an outline diamond is an NPC. That is a plan, not a shipped feature.

How this fits our bosses page

Our bosses page, written from pre-release material, lists Iskra as a returning Lieutenant and says details on her territory and loadout were not public. This video is the first source we have that says where she was found: the fourth floor of a building at Cheonwang Peak Array. Where they agree: both say a Lieutenant kill can pay a key to her loot room, and both treat the dog tag as the thing worth carrying out. Where they differ: kojiro51 says buying intel makes her spawn, and our page describes intel as a way to find a Lieutenant who may already be active. His one-magazine kill sits beside our page's note that Lieutenants are more durable than normal enemies. We attribute each to its source and will update both pages if a later source settles it.

What we haven't confirmed

We haven't re-tested this run ourselves. This page follows kojiro51's Japanese captions and his chapter list on the early-access build. The building, the door he prefers and the floor layout are on screen in his video. We have not placed them on our map. Whether the intel purchase makes Iskra spawn or only tells you where she is. How often she drops the key: he says occasionally. The one-magazine kill: his weapon is not named. The graphics tip and the hidden exfil skill are his claims. Prices, drops and timers are early-access numbers and may change.

Why this matters for Wing Mait

A solo boss run is a chain of small things to notice while you are busy: the floor you are on, your ammo, a stranger arriving, the exfil timer. Wing Mait is a tactical voice system that watches the screen only: it doesn't read game memory, inject anything or send inputs to the game. Wing Mait for MW4 DMZ is in development, and this page is a field note, not evidence of live DMZ callouts.

Source briefing

Run, steps and timestamps: kojiro51, "【COD：DMZ】10分で簡単ソロ周回！設計図、アップグレード用アイテム、3アーマーを入手する方法" (YouTube, 24 October 2026), 6 minutes 22 seconds. The wording is ours, paraphrased from his Japanese captions and chapter list. YouTube's English translation of the captions renders the place name inconsistently, so we took it from his Japanese. We have not matched his footage frame by frame. Please watch his full video for the route and the door. Thank you to kojiro51 for sharing it.
