You don’t know much at the beginning.

But what you know is: you want to get out and pay them back!

Saving Bob

for Half-Life

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

Your friend and fellow scientist, Bob, is missing. Rumour has it that he fled the country after selling company secrets, but you know he would never do such a thing.

Last time you saw him he was talking of “nearly exposing the administrators’ malpractice” and “preventing an accident that could destroy this world”. He wasn’t very specific about anything but he seemed sincere.”

ETC – Earthquake Test Centre

for Half-Life

Originally, ETC stood for Earthquake Test Centre, but now that’s been forgotten.

All that matters is that you find yourself in a BM-style base with aliens and army trying to kill you.

It’s clear that you need to find a way out.

In fact, there’s a working portal, if only you could reach it!

When the next thing you know, a rival company has hired a small ‘faction’ of troops to come in and collect the data from the mainframe(s). Your objective is to stop them using whatever means necessary! Even if it means destroying the mainframe! You can’t let this data leak!
