What changes the answer

Use the current in-game rules as the source of truth if the lobby wording differs from older guides. Community posts and videos about Brawl are useful for positioning ideas, but several were made before later mode reworks.

Version and evidence boundary

The official historical announcement confirms the 4-Player Brawl mode; the current 2.0 announcement does not provide a complete Brawl rules manual. This page deliberately avoids asserting an exact point cap, wave schedule, or current Brawl meta without a live rules capture.
