A new content patch, Corsairs Stronghold, has been announced for free-to-play MMO Tera. This patch introduces a new battleground, which allows two sides to defend and attack a castle. Players will have tanks, cannons, airships and siege weapons at their disposal. Here’s the announcement trailer:

The battleground is open to any players over level 30, and standardises gear for balance. The battleground also allows players to gain XP, meaning it can be used as an alternative to the quest grind for levelling up. TERA is available for download here.
