N51

Nevada 51 (or N51 for short) is a fan-made military group created by Darksignal. They were added into the game after Darksignal paid for the designer pack.

The group is fought in the Siege Mission Hard Sell, where they try to destroy an artifact that the S.Q extracted.

Units
N51 Recon - N51 Recons are the basic infantry of N51. They take cover in the staging room until they are commanded to rush towards the artifact. When not in the staging area, they will walk towards the artifact to try and unlock it, but will shoot anyone that crosses into their path.

N51 Assassin - N51 Assassins are the melee specialists of N51. They spawn behind the player and uses quick attacks in rapid succession to damage the player as fast as possible.

N51 Commando - N51 Commandos are higher class soldiers who possess tac bars and better weapons. Most just hang in the staging area until they decide to rush the artifact, but sometimes one of them will drop from the roof and try plant c4 to destroy the shutter doors to allow their fellow units a faster path to the artifact.

N51 Overwatch - N51 Overwatches are the snipers of N51. They hang in the staging area and when they leave the staging area, they hang in the back and try to snipe anyone attempting to stop their allies from destroying the artifact.

N51 Delta - N51 Deltas are the unarmed specialists of N51. Sporting a tac bar, two corpus blocks, leaping grapples, and lots of adrenaline being breathed in, they move around the arena with quick speed punching anyone that doesn't keep their distance.

N51 Officer - N51 Officers are the squad leaders of N51. Armed with M249s, they will spray and pray anyone unfortunate enough to cross their path.

N51 Mortar - N51 Mortars are the artillery of N51. Sporting a M32 grenade launcher, they blow most enemies to pieces. Unfortunately, melee hitting five times in a short period of time, like other G03LMs, will cause them to launch a tantrum throwing a flurry of punches tiring them out.
