Underground 2 in the browser
Which UG2 site is multiplayer
I refuse to treat “UG2 browser” as one product. The domains disagree.
Three sites
nfsu2.xyz says Chrome and Firefox can run online free roam and races, with saves in a local profile you can download and optional Cloud saves. That claim is one source: the site itself. nfsunderground2.site is a PS2 web recompile with a private two-player room and a virtual memory card. nfsu2.org states it is single-player and publishes the size of its data pack. A GBA page that ranks for the same query is a different, offline game.
Device support differs by host: nfsu2.xyz names Chrome, Firefox and touch input; do not impose another project’s WebGPU requirements on it. Clearing the site wipes the local save unless you exported it. None of these hosts is the 2003 Underground client at nfsu.online.
Questions
Which Underground 2 site is multiplayer?
nfsu2.xyz describes online races. nfsunderground2.site describes two players. nfsu2.org says single-player. I do not merge them.
Can I move a save between them?
No. The profile, the memory card, and the single-player key are different stores.
