Battle Cars will feature trophy support, YouTube uploading, custom soundtracks, online leaderboards and online voice chat. There will also be a video editor within the game, giving you lots of advanced options to edit the footage in-game, including adding slow motion to replays. Offline, the game will support 4 players, while online will support 8. Multiple players on a single PS3 can play together in online matches, so two PS3s with 4 players on each is entirely possible.
The game will launch with three maps, though more will follow. There's also the possibility that some DLC may be free, though that's unconfirmed as of yet (confirmed!). That's a lot of content for downloadable title, but with WipEout HD we've come to expect such things. Check out the gallery below for more Supersonic Acrobatic Rocket Powered Battle Cars screenshots and make sure you check out the next PlayStation Nation podcast on PS3 Fanboy later today for the full interview.
[UPDATE] Hagewood has confirmed that there will be free maps to download in the future.
