G-man man is asking you for another mission at Xen, this game is kinda difficult until you realise it. =P
A small pack replacing the old Low-Definition models from Redemption. I wouldn't recommend downloading this unless you have the High-Definition pack for the original Half-Life. Enjoy! How to install: Unzip it to your Half-Life folder which for the retail version of Half-Life would be ex. "C:\Sierra\Half-Life " OR for Steam ex. "C:\Steam\steamapps\accountname\half-life\"
