Acclaimed indie game Chivalry: Medieval Warfare (AusGamers 9.0/10) has become the latest game to earn the new R18+ sticker from the Australian Classification Board, following its submission in preparation for a boxed retail release later this month.

ACB's overview cites high impact violence, and strong impact themes, which is understandable given the appropriately visceral nature of the game's melee-focussed combat.

The game has received equivalent ratings in other regions, with a PEGI 18 (European 18+), and ESRB M (North American 17+), however none of these are noted on the game's Steam page, where the game was originally released digital-only, last October.

QV Software and Lace Mamba are bringing Chivalry: Medieval Warfare to Australian shelves on February 21st 2013, with a RRP of AU$29.95, only marginally higher than Steam's current US$24.99.
