Ground Zero 2: Fallout

for Opposing Force

In Ground Zero 1 you were Gordon Freeman. On your quest to the Lambda Lab, you find another one of the Black Mesa’s nuclear weapon storage facilities. This one is different though, a rogue group of military has stormed the building, and plans to detonate the weapon to rid the Alien invasion. You, becoming aware of this, must deactivate the nuclear device to save the innocent Scientists, and to prevent the destruction of the Black Mesa’s vast amounts of data, research and information.

Bootleg Squadrog

for Opposing Force

Single Player First Person Shooter Maps and Mods for Half-Life 1, 2 and Episodes 1, 2 and 3

“Bootleg Squadrog, sir. It is not about individualism. It is not about cowboy heroism. It is about being one cohesive unit. The only identity I have is that of a group identity.”

You are sent on a mission to recover Gordon Freeman, but as expected, things don’t go according to plan.

At least you have an escape route planned.

Go get him soldier!

Warzone

Author’s Note:“You are a special forces commando. You were in Black Mesa during “the accident”.

Now 50 marines including you, have been sent to this base which could be “Black Mesa 2”. This is where the small amount of captured aliens were taken.

But all hell has broken loose and you were knocked out and thrown in a small building. Luckily an alien grunt came by and dropped a huge load of pistol ammo! “Good luck marine!”
