Bring a spool of thread. Trust me.

Deep in a cavern near the Delta Outpost resides a swarm of dangerous creatures who would love nothing more than to destroy you and your squad. The Minos Caverns is not only home to dangerous Warnets but has been infiltrated by a Bane base, threatening the security of AFS. Ten Ton Hammer has your complete walkthrough for this instance detailing every mission and how to finish their objectives.

High on a ridge overlooking the Delta Outpost a sinister cavern awaits you and your squad. You'll want to bring more than a flashlight and some glowsticks for the gloomy Minos Caverns as you'll encounter a number of Warnets waiting to electrocute you. A brave AFS reconnaissance team has been sent in to explore the area but we've lost contact so it's your mission to find out what happened to them. You'll find that beyond the swarming Warnets lies a deeper darker secret you may not be prepared for.

Prepare for some spelunking at Ten Ton Hammer's TR site.
