Popular indie game Skullgirls is now a free-to-play mobile fighting RPG for iOS and Android. And while it does feature some of the annoying free-to-play stuff found in other games in the genre, it's got a surprisingly complex fighting game to back it up.

Indie fighter Skullgirls is bringing the battle to iOS and Android later this year, with a game that blends fighting game action with RPG mechanics to create something... well, just look at it.

The developers had to get their campaign extended despite being able to push their prototype onto Steam and the PSN stores. But now, with just over two days remaining, the creators of Skullgirls will be able to follow up their vision for Indivisible after the 2D action RPG surpassed its US$1.5 million target.

Briefly: Indivisible, the new RPG from the creators of Skullgirls, has been funded on Indiegogo to the tune of $US1.5 million. It wasn't looking good for a stretch -- they had to extend their funding period -- but 62 hours remain in the campaign.

Video: The team behind Skullgirls, Lab Zero Games, just announced Indivisible, a game "inspired by classics like Valkyrie Profile and Super Metroid". Looks cool, and in a nice touch, the soundtrack is being handled by Secret of Mana composer Hiroki Kikuta.
