A dramatic scene as two bikers, using a hidden helmet camera to record video, approach a secret back entrance to Area 51 and are held at gunpoint by unidentified men in camouflage gear, is going viral after being posted online.

The men, who describe themselves as "adventure tourists," had attempted to get close to the Nevada base once before, and declare at the beginning of the video, "hey camo dudes - we're back."

The video has been viewed over 230,000 times since it was posted on Monday.

"EVERYONE SHARE LIKE CRAZY, WE MIGHT HAVE TO TAKE THIS DOWN SOON DUE TO THE US GOVERNMENT!! DON'T LET THEM HIDE THIS!! This is raw and shot in realtime. Not fake or PHONY! We bring you the extreme footage shot by us. I don't know how long it will be up until the Gov't makes us take it down!" the caption on the video reads.

As they approach on their motorcycles, signs on the dirt road warn that "deadly force" may be used against trespassers.

"Put you're f***ing hands up, I'm not gonna tell you again," one of the unidentified men in camouflage shouts.

The bikers are frisked for weapons and asked why they are in the area, and one of the camo-clad men declares "We are going to give you guys a chance. You turn around and get the f*** outta here."

The bikers are warned that, if they are do not leave, the crypto-soldiers will call authorities in Lincoln County and they will be fined $750. The two thrill-seeking motorcycle riders then depart, lamenting how enjoyably exciting the incident was, and remarking on how aggressive the armed men behaved.

The US government did not admit that the fabled Area 51 was real until a Freedom of Information Act request confirmed it's existence in 2013.

Area 51 has long been a subject of intense interest for UFO hunters and alien enthusiasts who believe the base is home to extraterrestrial spacecraft that crashed nearby. The US military and saner heads point out that Area 51 is a testing site for surveillance aircraft, stealth bombers, and cutting edge aerospace technology.
