Ok I am totally BIASED here as a few of my models are in this DLC. But just played a bit in the alpha of this. THIS is the DLC to get if NEW to GTOS/APOS/k43 series. It is a good balance of terrain, force on force equipment and pretty quick action. AS a gateway drug into GTOS series....Highly recommended even in unfinished form.. There are more vehicles that are new coming for this DLC so old hands should have new toys to play with.
Preordering it will save you a few bucks and maybe the early money can help the dlc get better. Hooper was and is a good DLC... this one for new guys is better and for old hands is ALOT different than previous GTOS\APOS offerings.
