I hadn't played in a few weeks but another major content patch dropped on Tuesday. They've added a new map, Canyon Networks. It's about the size of Caustic Valley. I've had a few rounds on it now and I really like it. I love the verticality of the map which should provide JJ capable mechs some options.
Spoiler for size
They've also added another medium mech, the Blackjack. Lots of balances and tweaks also included.
