Induction

for Half-Life

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

This is a Russian mod, with English subtitles, that lets you play as Gordon Freeman before that fateful day.

As the name suggests it takes you through your induction and some training.

There’s no combat, but you do need to use your crowbar to help a fellow scientist.

Before

for Half-Life

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

Under certain radiation exposure this artifact opens a portal. Presumably the portal will lead to another artifact in the parallel world. Mission: Enter the portal and find the artifact in the parallel world. You will receive our new development, a suit that will allow you to safely get through the portal, and theoretically protect you from possible dangers in the parallel world. Once you have found the artifact, press this button on your suit and you will get teleported back to the Black Mesa laboratory.

Heart Of Evil: Napalm Edition

for Half-Life

Heart of Evil: Napalm Edition (HOE NE) is a remake of the original Heart of Evil.

Heart of Evil was an enjoyable Single Player modification that truly gave the player something different – “a Single Player Half-Life mod that accurately and sensitively depicts the American ‘experience’ in Vietnam, right down to the laces on the zombies boots.”

HOE NE will let veterans and newcomers alike relive that experience.

They put a lot of work into the original concept and we want to it endure.

For that reason we updated the mod as best we can. The source code was released publicly February 1, 2007. Shortly after, we started development. By shortly, we mean months.

HOE NE features updated Models, skins and animations; revitalized Maps with new effects, visual improvements and altered gameplay; tweaked NPC and weapon code.

This is a community project. That means it’s not for profit. All work will be properly credited to its respective owners. This is not a Source project/port.
