The New Weapons
There are some new Star Cards (Scatter Gun, Dioxis Grenade, and Adrenaline Stim) but I'm more excited about the new weapons coming in Outer Rim.
Battlefront is in desperate need of some new weaponry and the two guns coming in the Outer Rim DLC should finally provide that.
The other weapon, the Relby V-10 rifle, will likely be a grenade/mortar type weapon. The Relby is also the blaster rifle that was used by the bounty hunter Bossk.
Both appear to be unique and they're two more options for a lineup that, like the game modes, is starting to feel stale.
