Arriving at a disused military bunker, a group of friends is set to spend the weekend exploring the area for a special project they're about to start, but the longer they're there they come to believe a psychotic cannibal killer is loose within the facility and must find a way to avoid being eaten to get out alive.
This was a decent enough sequel but has some issues. One of the better elements here is the rather impressive atmosphere featured throughout here as this all comes off quite well. The main bunker where the group stays has the hallmarks of the cold, desolate military facility from decades earlier as the remnants of its original operations with the darkness, cold environments, dust-covered environment and desolate setup that leaves them alone offers the kind of scenario for a claustrophobic genre effort to be had. That leads into the film's best aspect here in the admittedly graphic and brutal gore in the various tortures and kills on display. As the killer keeps victim hostage to brutally mutilate them before outright killing them, this gets quite bloody and brutal before going for the over-the-top concepts to showcase some cheesy yet still effective gore. The few chases here aren't so bad and the final encounter here is rather fun with how it plays out including a decent enough twist that's enough to end this on a high note which provides some positives. There are some big flaws present here. The main issue is a decidedly underwhelming and generally lazy setup that has some big factors holding it back which mainly stem from the inability to spell anything out. This one never gives much of a reason for what their purpose to the bunker is supposed to be about or even who most of the girls' names are until they're shouted out in the middle of a chase, making for a difficult time to care about the group before they're being dismantled when we don't know who they are. It becomes even more problematic due to the troublesome killer here that's incredibly frustrating. Continuing on from the lack of knowledge dished out elsewhere, he doesn't get much about who he is, what he's doing holding them hostage to save for later while others he kills without a second thought or even how he survived all this time. As well, he lacks the imposing physically to be intimidating or the grotesqueness to be memorable, making the franchise connection tenuous at best leaving this one with some big drawbacks.
