The Raider Mech is described as a medium class unit that specialises in quickly closing the gap between yourself and opponents, before dealing out substantial damage at close range. It's a class B, has a Muller chassis, and is rated with a 4.0 difficulty.
This update also brings a stack of extra weapons and upgrades too, largely focused on short-range damage, to help you get the most out of the new Raider. Want fixes? Yeah, there are a bunch of these too. Full list here.
Finally, you can now use Mech Taunts to mock the opponents you kill. Each class has a pair of set phrases that you can unleash by tapping 'G', and they range from clichéd to downright cringe-worthy. You get one free for each class, and despite being a bit lame, they do neatly sidestep the embarrassment of being butchered as you diligently type out a full, weapons-grade insult towards the total stranger you just virtually killed.
