Cosmetic mods in Helldivers 2 are not officially supported and operate in a grey area; while developers have implied they won't proactively ban for strictly visual/audio changes, they are used at your own risk. The game's anti-cheat system (GameGuard) might flag altered game files as tampering, potentially leading to bans.

Here is what you need to know before installing them:

• Developer Stance: Arrowhead Game Studios has indicated they will not actively ban players for purely cosmetic or client-side mods.
• Anti-Cheat Risk: The game uses nProtect GameGuard, which may flag modified files as a threat. If you are automatically banned by the anti-cheat, the developers have noted they may not reverse it.
• Client-Side Only: These mods are strictly "client-side," meaning only you can see them. Other players will see your character in their standard, unmodded gear.
• Stability Issues: Game updates frequently break mods, which can lead to game crashes or error messages until the mods are updated.
• Mod Types: Popular cosmetic mods found on platforms like Nexus Mods include armor reskins (e.g., Star Wars or Halo themes), audio replacements, and UI adjustments.

Important: Never use mods that affect gameplay, such as those providing infinite health, ammo, or currency (Super Credits/Samples). These will trigger a ban.
