It is really up to what style of game play you prefer, if you like it simple, just run shoot and skoot, then I would prefer Kino Der Toten, if you like some cooler stuff and maybe harder levels, then propably the level "FIVE", but all together i would choose Ascension, it is a challenging yet unique style of gameplay, plenty of perks, weapons, and the mystery box always starts at the same place. and it is also much better for getting the hell out of a bad situation, if your on the ledge and you have that purple perk (i forgot the name, mah bad) you can jump and explode but survive on the bottom, there is long range sniping, plenty of gather spots for you and your friends to defend, and the best of all, a giant missile!!! yea no point to it but you can access the pack a punch when it launches.
