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.

A Soldier’s Tale

As part of the HECU, you enter the Black Mesa Research Facility via an armoured personnel carrier.

It leaves you in a large warehouse-style building and your objective is nothing more than to stay alive and kill as many enemies as possible.

Good Luck!

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!

Fallback, Fire and Ice

for Opposing Force

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

As Corporal Shepard, you are part of a platoon of marines supplying additional security at Monte del Oscuro (an astronomical research facility). Things never work smoothly as usual. Find a way to escape and lead your men to safety. There is a flashback to a Balkan Town to rescue a UN Representative from some warlords.

Finally, Ice, a massive set of levels set in Antarctica.   Something has been found in the ice and a number of foreign powers desire it.   After the little accident at Monte del Oscuro, you have been given a hardship posting. Defend the base against hostile forces and rescue the scientists!
