Took me around 5-6 hours to beat this so it's like ~2/3 size of main campaign which is great. Levels once again are well made and very detailed, maybe even more than in the base game. New additions like extra weapon/ammo and enemies are well welcomed as well. Vehicle parts were pretty cool and add something unique to the gameplay for a while. Overall it's great DLC and if you liked the base game, this one is great deal even for full price.
Great level desing that is detailed and very good looking. All the weapons are fun to use and feel good when using. Enemies are also great and soundtrack is very well made too. I don't think I have nothing negative to say about this game. If you like "boomer" shooters, this one is very good.
