BigWave — File Type Guide (AVS03)

What’s confirmed about BigWave

• BigWave is a file type — one of the 33 file types at launch.
• It is one of only three publicly named files, with LemWire and Defrag.
• The name is 2003-internet nostalgia: the download so big it floods the connection — and in a survivor-like, a “big wave” of anything usually means one thing.

What’s pending verification

• BigWave’s in-run effect or reward.
• Whether the name hints at a horde-wave interaction or is pure theming — unconfirmed either way, and we won’t guess.
• Spawn rate and rarity.
• Interactions with plugins, weapons or the Safe Folder mechanic.

Tested answers land here from September 28, 2026, each tagged with its game version.

Where BigWave sits in the systems

Files are the in-run collectible economy — the full picture is in the files hub. How they feed the between-run loop is covered in BeanZ and meta upgrades, and the difficulty folders that shape each run in protocols and policies.

FAQ
