Defiance is getting its first major content pack on Aug. 20, and bringing some basic changes to the core game at the same time.
When it launches, the Castithan Charge Pack will add new events, weapons and modes to Defiance. However, those who choose to pay $9.99 for the add-on (800 Microsoft points) -- or have the Season Pass -- will get some additional benefits as well.
The basic game changes include new charge weapons; a content mode called Siege where players must hold mission locations as enemies attack; an Arkfall event; a PvP capture-and-hold map called Military Academy; a Dueling mode; and some UI changes to the map and chat.
The paid content will include a playable Castithan alien (you can do a one-time change to make an existing character an alien); a Battle Arena mode that offers a mission storyline and a new Charge Blade Weapon; a Raptor vehicle to carry four players; a Castithan outfit; and special Xbox 360 and PlayStation 3 achievements.
