More importantly, the skill level is higher. Players on S1x are there because they love the advanced movement—expect to be boosted, dodged, and slammed by veterans who never left. S1x is part of a growing movement of community-led preservation in AAA gaming. When publishers abandon older titles, the multiplayer effectively dies. S1x proves that with enough technical skill and passion, a game’s lifespan is not determined by corporate server shutdowns but by the players themselves.
For competitive players or those who simply want to practice movement, S1x allows full offline play with bots, as well as LAN functionality. This has made the client a staple for small grassroots tournaments and private game nights.
One of Advanced Warfare ’s biggest PC failures was the plague of aimbotters and invincibility hackers. S1x integrates a community-managed anti-cheat that, while not perfect, has drastically reduced the number of rage hackers in public lobbies. Cod Advanced Warfare S1x
Enter —a community-made client that has surgically repaired, enhanced, and repopulated the game. What Exactly is S1x? S1x (pronounced “S-one-ex”) is not a mod in the traditional sense; it is a standalone client and launcher for Call of Duty: Advanced Warfare on PC. Developed by the team behind Plutonium (the famous Black Ops II client) and later maintained by the XLabs community, S1x bypasses the broken Steam and Activision matchmaking servers.
The base game’s supply drop system—loot boxes for weapon variants—was widely disliked. S1x allows server hosts to enable an “unlock all” option, giving players access to every weapon, variant, and cosmetic instantly. This levels the playing field and lets players focus on gameplay, not gambling. More importantly, the skill level is higher
Instead, it provides its own server browser, anti-cheat system, and a host of technical fixes that the official game never received. 1.

S1x replaces this with a classic server list. Players can see exactly which servers are active, ping times, player counts, and map rotations. You click, you join, you play—no waiting.
In the pantheon of Call of Duty’s jetpack era (2014–2017), Call of Duty: Advanced Warfare often sits as the ambitious, exoskeleton-clad middle child. It introduced verticality, boosting, and dodge mechanics to the franchise, but over time, its official PC version was abandoned to hackers, dead lobbies, and a non-functional matchmaker. This has made the client a staple for
S1x patches memory limits, fixes the infamous “memory error” crashes on high-texture settings, and uncaps the frame rate beyond 91 FPS (which was hard-coded in vanilla). Mouse input lag has also been significantly reduced, making the twitchy exo-movement feel responsive again. How to Get S1x Running Unlike some revival clients that require piracy, S1x operates in a legal gray area: you must own a legitimate copy of Call of Duty: Advanced Warfare on Steam (or have the game files). The S1x installer then reads those files and builds a separate, modifiable client instance.
