DMA setup for Arena Breakout: Infinite: ACE and DMA Guard
Arena Breakout: Infinite runs Anti-Cheat Expert plus DMA Guard, a layer built against hardware memory reading that requires VT-d or IOMMU enabled in BIOS. What to check before buying.
Short answer
Arena Breakout: Infinite runs Anti-Cheat Expert (ACE) plus DMA Guard, a layer built against hardware memory reads. DMA Guard needs VT-d or IOMMU enabled in the game PC's BIOS, so read the live status board before you buy anything for this game. This store sells an external cheat for it (/products/arena-breakout) and a DMA cheat with a Direct build (/products/arena-breakout-dma).

Which anti-cheat does Arena Breakout: Infinite use?
On PC the title is Arena Breakout: Infinite, and its Steam store page declares its kernel-level anti-cheat by name as Anti-Cheat Expert. That is the same ACE product used by other Tencent-published titles. In the August 2026 update, Morefun's security division added a second layer of its own called DMA Guard, and the name is not marketing borrowed from somewhere else. DMA Guard's stated purpose is preventing external hardware from reading game memory, which is a plain description of the DMA architecture itself.
What is DMA Guard reported to require?
Morefun describes DMA Guard as a hardware-level memory-protection feature that uses CPU virtualisation and live memory encryption, so memory read from outside is scrambled. The requirements below come from the game's own error guidance and from community fix guides, so verify them against the client in front of you.
| Item | What it is | Why it matters here |
|---|---|---|
| VT-d (Intel) / IOMMU (AMD) | The platform feature that mediates which memory a PCIe device may access | Reported as required for the game to launch on flagged accounts. This is the setting most DMA guides tell you to leave off |
| CPU virtualisation (VT-x / SVM) | The master virtualisation toggle in BIOS, a prerequisite for the above on many boards | DMA Guard is described as using virtualisation to contain and encrypt engine memory |
| Kernel DMA Protection | The Windows feature that sits on top of platform IOMMU support | DMA Guard is described as building on it rather than replacing it |
| ACE kernel driver | The kernel-level anti-cheat the store page declares | The familiar layer. The second-PC architecture addresses this one and not DMA Guard |
The settings that satisfy DMA Guard are the opposite of what most DMA builds ask for. That is not a coincidence, and it should not be treated as a minor detail.
Warning
Why this is the most hostile title in the catalogue for DMA
The stack is a kernel anti-cheat plus a dedicated layer named after DMA. Add encrypted engine memory and a platform requirement whose job is to mediate PCIe memory access, and you have a stack designed against hardware readers. None of this says whether a build currently works, because that is the status board's job. Do not buy hardware for this title on the strength of a product page, a forum post or a seller's confidence. Check the live status board first, and ask before you spend.
What hardware does an Arena Breakout build need?
The shape is the same as for any extraction shooter, with the card and firmware in the game PC and the reader on a second PC. A second screen or a fuser shows you loot, players and exits, and aim assistance adds an input device the game PC accepts as an ordinary mouse. On this title, though, the question is not the shape but the platform requirements. Work out whether the game PC can satisfy DMA Guard and host a card at the same time before you think about features.
What should you check first, and in what order?
On every other title in this set the first step is booting a machine, but here it is reading a status row.
- Read the live status board row for this title before anything else
- Confirm the game launches on its own on the game PC, with ACE and DMA Guard satisfied and no reader attached
- Note exactly which BIOS settings the game required to launch, because that is your constraint
- Boot the second PC and confirm the card enumerates
- Start the reader and attach to the card
- Launch the game and let both anti-cheat layers finish starting
- Attach to the game process only once you are in a raid
- If a fuser is in the path, run borderless windowed and match resolution and refresh on both machines
Pre-raid checklist for Arena Breakout: Infinite
- You read the status board row for this title today, before planning the session
- The game launches cleanly on its own with the BIOS settings it demands
- You know which of those settings your build would need changed, and that the game will stop launching if you change them
- The card is in its data port and the reader attached before the game launched
- You have not taken a seller's word over a current status row
- Borderless windowed is set if a fuser is in the video path
- You accept that this title's anti-cheat stack is explicitly aimed at this hardware class
Common Arena Breakout problems and how to fix them
| Symptom | Likely cause | Fix |
|---|---|---|
| Launch blocked with a DMA Guard or hardware-feature message | VT-d or IOMMU is not enabled on the game PC, or the master virtualisation toggle is off | This is the game telling you what it requires: with the setting enabled the game launches, and with it off the game does not. There is no third option |
| BIOS option is greyed out or absent | Board-dependent. Some boards gate IOMMU or DMA protection behind other settings, including Secure Boot state | Consult the board's manual, change one setting at a time, and record the working combination before you experiment further |
| Game launches, reader attaches, nothing readable | Possibly build state, possibly the memory-encryption layer this title added | Check the status board rather than chasing this with configuration changes, because on this title an empty read is more likely to be build state than a fault |
| Worked before the August 2026 update, stopped after | That update is when DMA Guard shipped | There is nothing on your side to fix, because this is an architectural change in the title, not a fault in your stack |
Common questions about Arena Breakout builds
Which anti-cheat does Arena Breakout: Infinite use?
It uses Anti-Cheat Expert (ACE), declared by name on its Steam store page under the kernel-level anti-cheat disclosure. It also runs DMA Guard, a hardware-level memory-protection layer from Morefun's own security division that was added in the August 2026 update.
What does DMA Guard actually do?
Morefun describes it as using CPU virtualisation and live engine-memory encryption, so that memory read by external hardware is unreadable. It sits on top of platform IOMMU support and Windows Kernel DMA Protection. The full mechanism is not published, so treat specific claims about it with suspicion.
Do I have to enable VT-d or IOMMU to play?
The game's own error guidance points there, and community fix guides report launches being blocked until it is enabled. Confirm against your own client: if the game refuses to start until you enable it, that is your answer, whatever any guide says.
Should I buy hardware for this title?
Check the live status board first, and ask before buying. The anti-cheat stack is aimed at hardware readers, which on its own does not tell you whether a build works today. That makes a current status row the only sensible basis for spending money.
Is the mobile Arena Breakout the same thing?
No. The mobile game is a different client from Arena Breakout: Infinite on PC, with a different anti-cheat posture, so none of this applies to it.
Info
Does anything work on Arena Breakout today?
The architecture is documented and dated, but current state is not. On this title, state can change with a single update, as the August 2026 DMA Guard rollout showed. The live status board is the source of truth, showing the game's own build date next to the status date. On this title more than any other, read it before you buy.
Sources
The ACE and DMA Guard details come from running the build rather than from a listed source, and the August 2026 update changed the whole picture at once.
