Dear Operators,
In our previous briefing, we introduced the Anti-Cheat Expert (ACE) system. Today, we are getting technical by addressing a specific type of threat that has plagued the First Person Shooter genre: Hardware Cheating.
You've likely heard rumors of "undetectable" cheats—devices that plug into a PC and read game data without the game ever knowing. These utilize DMA (Direct Memory Access) cards. For a long time, these were the "boogeymen" of tactical shooters, ruining matches in highly competitive maps like Space City and Tide Prison.
This December, that is going to change in Delta Force with the newly launched upgrade: DMA Shield, an Enhanced Hardware DMA Protection feature. Building upon the existing Windows 'Kernel DMA Protection' security feature, it further enhances protection against abnormal external hardware and prevents unauthorized memory access by external devices to avoid DMA attacks, thereby protecting your account from malicious exploitation.
Here is your plain-language intro to our newest defensive upgrade: DMA Shield.
ACE Intel: DMA Shield
To understand the solution, you have to understand the problem.
Normally, your computer's processor (CPU) acts like a traffic cop, checking everything that moves in and out of your memory (RAM). However, for speed and efficiency, modern computers allow certain hardware (like graphics cards or sound cards) to bypass the traffic cop and talk directly to the memory. This is called Direct Memory Access (DMA).
Cheaters exploit this. They plug in a malicious DMA card that secretly reads your memory to see enemy locations (Wallhacks) or adjust your aim (Aimbots). Because this card bypasses the CPU, traditional anti-cheat software often can't "see" it.
VT-d (Virtualization Technology for Directed I/O) is the technology that puts the traffic cop back in charge. It essentially creates a secure, locked container around the game’s memory.
ACE Mechanics: How We "Trap" the Intruder
Think of your game’s memory like a massive, secure warehouse.
● Without VT-d: The warehouse doors are open. If a cheat device has a badge (DMA access), it can walk in, look at the inventory (player positions), and leave without the security guard noticing.
● With ACE & VT-d: We re-organize the warehouse. When a device tries to access memory, the system acts as a decoy.
If a legitimate device (like your GPU) asks for data, it gets the correct location. However, if an unrecognized or "abnormal" device (like a cheat card) tries to access that same data, ACE’s protocols ensure the address is "Remapped." It sends the cheat device to an empty room or feeds it garbage data. The cheat tries to look for enemies, but it sees nothing but a blank wall.
Global Recon: Why This is the Gold Standard
We aren't just experimenting here; we are adopting a industry-proven strategy.
In the competitive world of FPS, VT-d and DMA protection are widely regarded as the "endgame" for anti-cheat. Major competitive titles that require the highest level of integrity—games where millions of dollars in tournament prizes are on the line—have pushed hard for these hardware-level security measures.
The industry consensus is clear: Software-level protection is no longer enough. To stop modern cheaters, you need hardware-level isolation. By implementing this, Delta Force and ACE are aligning with the most secure competitive ecosystems.
Mission Outcome: Neutralizing the "Invisible" Threat
Here are a few things to expect when we activate this protocol in December.
● Hardware Bans that Stick: If a DMA card is detected trying to bypass the DMA protection, ACE can flag the specific hardware signature. This makes it incredibly difficult for the cheater to simply "make a new account."
● Disarming the Radar: Those impossible moments in Tide Prison where an enemy seems to know your location instantly? Those will drop significantly. DMA radar cheats will be effectively blinded.
● Sanitizing the Ecosystem: This raises the barrier to entry for cheating. DMA cheats are expensive and complex; by rendering them ineffective, we remove the incentive for players to buy them.
We know that no anti-cheat is 100% cheat-proof forever. However, DMA Shield forces cheaters to jump through hoops so high that most will fall.

Next up: In our next brief, we will explain the second half of the December Protocol—Secure Boot and TPM 2.0—and why trusting your boot process is vital for a fair fight.
