TLDR: Maps are fun. New scout is really cool. New truck is different and interesting. New specialist is good for co-op/rescuing other trucks. The new maps are basically the above ground and below ground of the same area. The above ground is my favourite desert/canyon map in the game. It deceptively has a lot of climbs which make for stunning views. The below ground is fun and different to traverse while acting as alternate routes to take for the above ground. The Shiba Overlander is my favourite looking scout with access to the free dlc rock climbing winch, making it an utter beast. The albatross is a cool new 'offroad' truck with front and rear steering making it really nimble but does struggle with power (with stock engine anyway). The new specialist is really focused at saving other stuck vehicles which could really be useful in co-op or if you haven't unlocked all the stuck trucks in the game.
