Ok after seeing the trailer and seeing the screen shots above this is my takeaways:
1. Choices of Mechs. Archer, Warhammer, Marauder, Rifleman, and the Phoenix Hawk (THANK YOU SWEET BABY JESUS!!!) are excellent choices to bring into the game. The Assassin, Vulcan, and Flea not so much as I would have rather have the Stinger, Wasp, Wolfhound, or even the Clint. The Annihilator is an interesting choice to be sure. I don't like it and I don't hate it...its just interesting. The Bull Shark, I am going to reserve judgement until I play with it or against me.
2. New Weapons. I like it, but with that being said I hope that the up the found ammo for existing weapons (looking at you Gauss Rifles), they reduce the tonnage and space requirements on the ECM and Active Probes to what they are in the table top game, and add in the half ton MG ammo option.
Overall I am thrilled and can not wait till it gets here!!!
