Delta Force Anti-Cheat: How ACE and G.T.I. Security Work

Delta Force uses Anti-Cheat Expert, known as ACE, as its anti-cheat system, run alongside the developer's own G.T.I. Security team. On PC it combines client, signature and behavior detection with Windows protections such as Secure Boot, TPM 2.0 and a DMA Shield, and as of November 2026 it is backed by Operation Sentinel, a system that isolates repeat offenders, plus weekly ban notices, gear compensation for victims and legal action against cheat sellers.

Everything in this guide comes from the developer's G.T.I. Security posts and patch notes on Steam, dated December 2024 through October 2026, and the game's End User License Agreement, all checked in November 2026.

What Anti-Cheat Delta Force Uses

In its first Security Brief, published on November 28, 2025, the developer introduced ACE as the primary tool in its arsenal. ACE was established in 2005, and the developer describes it as a one-stop security system covering the game client from mobile to PC. On PC it uses several layers at once, including client anomaly detection, cheat signature detection and behavioral anomaly detection, so it looks at how a client behaves rather than only searching for known programs.

On phones, ACE takes what the developer calls a prevention-first approach: anti-debugging, code protection and resource hardening that make it harder to tamper with the game files. A third pillar targets the economy, with models that look for illicit real-money trading around the Auction House. The same brief said that over 170,000 accounts had been banned during 2025 for confirmed violations of the terms of service.

G.T.I. Security, the in-game name for the security team, publishes a "Notice of penalties for violations" on Steam most weeks, plus longer briefs when something significant changes. Reading a few of these posts is the quickest way to see what the team is focusing on at any given time.

Why the Game Asks for Secure Boot, TPM and DMA Protection

Many PC players first meet the anti-cheat through a pop-up asking them to enable something in their BIOS. In December 2025 the developer published two guides explaining these prompts. The first covers Secure Boot and TPM, Windows 10 and 11 security features that make sure your PC only loads trusted software at startup. The guide walks through checking that your system disk uses the GPT partition style, confirming that the BIOS Mode is UEFI, and then enabling Secure Boot and TPM, choosing version 2.0 where offered.

The second guide covers the DMA Shield, which the developer describes as ACE's enhanced hardware DMA protection. It builds on the Kernel DMA Protection feature in Windows to stop unauthorized external hardware from reading memory. Enabling it usually means turning on virtualization and DMA protection options in the BIOS, whose names vary by motherboard brand, and the developer notes that the requirement may be applied to accounts that show signs of an abnormal login environment as a preventative measure.

• If you see a Secure Boot or TPM prompt, follow the official guide rather than random forum advice, and contact your motherboard maker if your BIOS looks different.
• If a DMA prompt appears, it does not mean you are accused of anything; it is a precaution tied to the login environment.
• Back up important files before changing disk partition styles, since that step touches your system drive.

Operation Sentinel: How Repeat Offenders Are Handled

The developer admitted in June 2026 that a small group of determined cheaters did not care about losing accounts and simply made new ones, causing an outsized share of the damage on Hard maps like Space City and Tide Prison. Its answer was Operation Sentinel, launched in the first week of June 2026 as an extra enforcement layer on top of detection and bans.

When the system flags a device for high-risk patterns such as ban evasion or rapid account cycling, the linked accounts enter a restricted state:

• In Operations, they can only access Zero Dam and Layali Grove.
• Squad play is disabled and their matchmaking pool is separated from everyone else.
• They are visibly marked to other players in the match.

Flagged accounts go through an observation period. Normal play can lift restrictions early, finishing the period cleanly removes them, and another anomaly extends or escalates them. For confirmed chronic offenders, all illicit gains are clawed back, and accounts that benefited from carry services face the same treatment. If you believe you were flagged by mistake, the developer asks you to contact official support for a review.

What Can Get Your Account Penalized

Most players never come close to a ban, but a few rules surprise people because they do not feel like cheating. The developer's December 2024 list of prohibited and not-recommended software is the best reference. It prohibits running certain categories while the game is open, including DMA hardware and hardware macro devices, memory analysis and debugging tools, speed-changing software, scripts that simulate keystrokes and virtual machines. It also lists remote desktop and game streaming tools and frame capture tools as not recommended, warning that using them may trigger error pop-ups or penalties depending on severity.

Other rules worth knowing:

• Editing config files: in June 2025 the developer announced 7-day bans for players who modify .ini configuration files to change grass, trees, smoke, characters or brightness, with harsher penalties for repeat cases.
• Abusing matchmaking to move items: in October 2026 the team said it would recover all Tekniq Alloys gained by moving supplies between matches through queue sniping, a form of illegal real-money trading.
• Unofficial top-ups: buying currency through unauthorized services can lead to penalties, and the developer cannot help recover losses from them.
• Teaming with cheaters: the Security Code of Conduct lists teaming up with cheaters and manipulating matchmaking as violations.

The game's End User License Agreement also prohibits sharing information about cheats, hacks and exploits in videos, so this guide sticks to how the protection works and what to avoid.

Reporting Cheaters and Getting Your Gear Back

Reports feed directly into investigations, according to the developer, so include as much detail as you can: the match, the time and what you saw. The official channels are the customer service icon, shaped like a headset, on the login screen or anywhere in the game; the Support section of playdeltaforce.com; and the customer service email address listed in the security posts.

If a cheater kills you in Operations, you may not have lost your gear for good. Under the developer's compensation policy, once that cheater is confirmed and banned for 10 years, the gear you brought in through your equipment slots (weapons, attachments, helmets, vests, backpacks and chest rigs) is returned by in-game mail, usually within one to three business days. Items stored in containers and consumables are not covered, and you do not need to have reported the cheater to qualify. Our Hazard Operations guide explains why protecting your equipment slots matters in raids.

Habits That Keep Honest Players Clear of Trouble

Automated systems look for unusual environments and behavior, so a little housekeeping reduces the chance of an error pop-up or a precautionary prompt.

1. Close background tools before launching. Remote desktop apps, streaming hosts and frame capture utilities are on the not-recommended list, so shut them down unless you truly need them.
2. Leave game files alone. Performance tweaks that edit configuration files have already led to bans; use the in-game graphics settings instead.
3. Play on hardware you control. Virtual machines are prohibited while the game runs, and shared or borrowed machines may carry software you do not know about.
4. Buy currency only through official stores. It protects both your money and your account standing.
5. Avoid carry services. Operation Sentinel explicitly extends enforcement to accounts that benefited from carries, even if you never touched a cheat yourself.

If something still goes wrong, keep screenshots of any error message and contact support quickly. A clear record of what happened makes reviews faster.

How the Fight Has Gone in 2026

The developer's July 2026 mid-year review said that over the previous six months it had moved detection earlier, added DMA Shield, Secure Boot and TPM 2.0 to its stack, improved detection of kernel-level stealth cheats from April, and launched Operation Sentinel in June. It reported that cheat activity was trending down while warning that the problem is never fully fixed.

In September 2026, G.T.I. Security described supporting a criminal investigation into a ring that built and sold cheats for the global servers, with more than 30 people taken into custody, including studios that sold paid carry services. Players worried about fairness across platforms can also look at the console-only option described in our crossplay guide, and phone players can read how protection works on their side in the mobile guide. If you see someone selling "free" items or codes in exchange for logins, our codes explainer covers where legitimate rewards actually come from.

A Note on Accounts

Because enforcement works at both the account and device level, history matters. The store's Delta Force page lists accounts from outside sellers for players who want to start further along, and each listing describes its own details. Before considering one, read the EULA from Proxima Beta, which says players may not sell, resell, rent, lease or share a game account, or give anyone else access to it.
