Warzone

for Opposing Force

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

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!”

Retaliation

for Opposing Force

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

Author’s Note: “Retaliation picks up where Dark Operations left off. There will be no Xen or displacer in Retaliation.

Action is the main theme. It will mainly be an encounter against military targets, but there is a healthy dose of aliens too.

There will also be many sequences and a few puzzles to keep things interesting. Retaliation is the last of this series. Enjoy.”

Be sure to read the hints in the readme if you get stuck.
