Under The Hunter's Moon's a better expansion pack. Actually made me wish the main campaign had resource management, instead of the functionally infinite constant stop start of using a weapon, then recharging your energy over and over only at the cost of time itself.
The balancing's as wack as it always was only now Aliens spawn ceaselessly to drag out the playtime, not even counting the cool in theory but awful in practice wildlife, especially the f**king worms that can and will pop up bloody anywhere. There's only really one Alien level, the story goes nowhere instead of expanding upon any of the many compelling threads of the main campaign, and the tone's all kinds of just cartoony. The level design's also pretty horrendous.
