Across repeated Chapter 10-11 runs, the same pattern kept appearing: most lost time on the ATAG by treating it like a normal side unlock. It is not. The robot mount is gated first by story progression, then by factory access, then by a narrower set of mechanical and Sanctuary materials. Once that sequence is understood, the route becomes much more efficient. In practical terms, expect one Chapter 10 story push plus roughly 60 to 90 minutes of focused farming for a stable first craft, then an additional session if you want the stronger upgrades and a much cleaner cooldown cycle.
The main point to keep in mind is that recent player reports are consistent on the broad structure but not always on the exact trigger. The ATAG is introduced during Chapter 10 content, often tied to a mission name that changes by localization, and some guides place permanent crafting access at the end of that chapter while others place it just after the Chapter 11 transition and a follow-up artisan interaction. That uncertainty matters because many players start farming long before the blueprint or craft option is actually available.
Do not begin with open-world material loops. Begin with the story gate. Open your Journal, track the main quest, and push directly into Chapter 10 objectives. Reports consistently connect the unlock to the Chapter 10 war sequence, the Gortac-orc related chain, and a story section where the ATAG is used in combat before it becomes a persistent system. If your save has not reached that section, every crafting detour is premature.
This is the first major filter. Most failed unlock attempts come from assuming the tutorial-style ATAG segment means permanent ownership has already been granted. In practice, the game appears to use that segment as proof of concept. Permanent use is tied to the follow-up systems: plans, materials, and research. If there is no craft option yet, the correct fix is almost always more story progression, not more grinding.
The efficient route is linear. Push the main story until the ATAG is introduced in battle. Stay disciplined here. Do not branch into loot runs unless the story explicitly sends you toward a factory, a workshop, or an institute. After the introduction, check every relevant interaction point tied to manufacturing: the factory, any artisan or smith associated with plans, and research-style NPCs. Depending on localization, the relevant mission may appear under different names, so follow the objective marker rather than relying on one exact quest title from outside guides.
What you are looking for is one of two outcomes. Either the ATAG blueprint becomes visible immediately in a factory crafting interface, or the game forces one more step, usually a conversation or handoff that happens right after the initial ATAG story sequence. Some recent coverage also places the permanent craft behind speaking with a specific artisan after the chapter shift. If the blueprint is absent, advance the next mandatory story node before assuming something is bugged.
This next part is where progress often stalls: players gather random metal parts instead of the specific progression materials the ATAG actually cares about. Once the blueprint is available, switch from story mode to targeted farming. Only then does the time investment start paying off.

Recent player guides broadly agree on the material categories even if they differ on the best exact map pins. The ATAG route pulls from three buckets: factory plans or blueprint access, electronic and mechanical components, and Sanctuary-linked items or effigies used for later upgrades. Some guides also mention rarer bottlenecks such as power cores, abyss cells, cog wheels, small batteries, and a Core of Benediction for deeper weapon or performance branches.
The reason for that order is efficiency. Early ATAG value comes from simply making it permanent and usable. Rare upgrade materials do nothing for you if the base platform is not crafted yet. Likewise, hard-farming Sanctuary items before you have institute access or a defined upgrade branch tends to create dead inventory instead of immediate power.

The best loop is a short rotation between a factory-adjacent combat area, a mechanical enemy route, and one nearby Sanctuary objective. The idea is to combine your material categories in one cycle rather than spending thirty minutes on a single resource that stops being relevant. Mechanical enemies are the obvious target because they overlap with the named component types most ATAG paths use. Human camps may still drop saleable loot, but they are generally inefficient for this specific goal.
A practical loop looks like this: clear a clockwork-heavy zone for component drops, return to the factory or research hub to check whether you have met a blueprint or upgrade threshold, then pivot to one Sanctuary clear for effigies or related items. Restock, reset, and repeat. If you are getting mostly generic crafting scraps, stop and relocate. For the ATAG, generic metal is less important than explicitly mechanical parts. That distinction saves a significant amount of time.

There is also a pacing issue. Do not spend an hour overfarming low-tier components before checking the next upgrade requirement. The ATAG path tends to shift bottlenecks. Early on, common mechanical parts are the limit. Later, research or Sanctuary requirements become the real brake. Efficient play means checking the next craft or upgrade recipe after every short loop rather than assuming you still need the same material stack.

For practical play, the strongest upgrade order is not “weapons first.” The ATAG becomes valuable when it is available often, survives long enough to matter, and moves cleanly. Damage upgrades look attractive, but they are inefficient if the summon window is short or the cooldown remains punitive.
The logic is straightforward. A durable, frequently available ATAG improves both combat and travel. A glass-cannon ATAG with a long cooldown improves neither for very long. If you are choosing between a flashy weapon unlock and a cooldown-supporting branch, the second option usually has the better return. That is especially true in Chapter 10 and early Chapter 11 when material income is still uneven.
Recent guide material consistently points to scientific institutes as the place where the ATAG stops being a one-off machine and starts behaving like a scalable system. This is where many players make the wrong read and spread materials across too many branches. The efficient approach is to use institutes as breakpoint tools: unlock one practical gain, test it immediately, then commit to the next gain only if it solves an actual problem in your current content.
For example, if your ATAG feels fragile, shift institute spending into durability and power before touching advanced weapon nodes. If it survives well enough but spends too much time unavailable, prioritize the branches connected to recovery or energy behavior. If a recipe suddenly asks for Sanctuary items or rare power cores, pause and verify that the benefit is worth the detour. Not every upgrade has the same impact on normal play.

This is the late-stage efficiency layer. Several recent player guides point to Emergency Power Units as the tool that changes the ATAG from “strong but inconvenient” into something much closer to consistent deployment. Depending on your upgrade state and supply, these can either remove the worst part of the cooldown or at least soften it enough that the mount becomes practical in back-to-back encounters.
The correct use case is not every minor skirmish. Save Emergency Power Units for three scenarios: chained boss or elite fights, long traversal sections where remounting saves time, and difficult multi-wave encounters where losing the ATAG at the wrong moment causes a reset. If you burn them on routine trash pulls, you are converting a strategic resource into convenience only. That is rarely efficient until your supply route is stable.
Once your factory craft, institute research, and Emergency Power Unit supply are all functioning together, the ATAG starts to feel effectively “always on.” That is the point where weapon upgrades become more attractive, because the platform is finally present often enough to justify deeper investment.
The underlying pattern is consistent: ATAG progress is efficient when treated as a linked system of story gate, factory craft, research branch, and cooldown control. If one of those four is missing, the entire path feels worse than it actually is. If all four are active, the robot mount stops being a novelty and becomes a reliable part of Chapter 10 onward progression.
