Alien Nanites build on Season 6's foundation with a sci-fi twist, enabling low-gravity zones that disrupt build battles and launch players skyward. As a throwable, they create an anti-gravity field in an alien biome—perfect for evasion or aggressive plays.

More crucially, they're a premium crafting material for upgrading weapons. A single Alien Nanite converts one standard weapon into its alien version, boosting firepower and thematic flair. Here's how the upgrades work:

Spot Alien Nanites as ground loot, especially in alien-infested zones. Collect them, open your crafting menu, and apply to eligible weapons for instant upgrades. Pro tip: Stockpile in high-risk areas for late-game dominance.
