Indie BioShock-looking mini golf adventure, Vertiginous Golf, has just had an update to its Steam Early Access content, with new multiplayer modes now available.

Publisher Surprise Attack Games has today revealed new content available for the off-the-wall golf title:

Arena mode - players need to sink their ball into holes spread across the spiraling course to "control" them. Picking up the coloured eggs will unlock special attacks that can be performed by controlling your hummingbird, allowing you to attack your foes and defend your turf. It takes a few turns to get the hang of, but it's a crazy amount of fun.

Race mode - there are a few race courses in the game where you will be trying to navigate the course as quickly as possible. Once again you collect eggs to unlock fuel for your Influence Bug, and weapons to mess with your competition. You can also turn weapons off in this mode if you want the feeling of a pure race, but where's the fun in that :P

Classic - this is essentially the same as the offline multiplayer where you simply play a game of golf. There are a few handy twists available; first of all you can turn weapons on or off which spices things up, and you all take your shots at the same time which means you aren't sitting there waiting for your friends to make a move.

To celebrate this, the game is also currently 50% off on Steam (less than USD$8).

Watch a trailer for the new modes embedded below.
