Optimum Fear mod for Half-Life

Three years ago, my newly founded work associates and I started work on a portal experiment that went horribly wrong, due to “unforeseen circumstances”. Between our world and Xen, a horrifically violent alien world, a large rift in the fabric of space and time was formed. This allowed all manner of violent species to come, uninterrupted, through the portal and vanquish the Earth. They caused the apocalypse as we now know it.” “From this new, unstoppable threat, humans split and formed factions deep underground in military, storage and research bases. Competition was fierce and grudges easily made, we carried on fighting for two years, through the system of railways that linked the bases, while the aliens controlled the surface.”

“My group, once a large faction had been pushed back, subdued and generally battered by the likes of the military and other groups. Three months ago, we took control of a small storage facility base, containing useful supplies and a test centre for explosive material. It was a mighty victory, compared to our recent luck. However, we could not keep it protected enough to keep it secure, and today, we lost all contact after a frantic message describing aliens and military personnel taking control of the base. It is my mission to blow these bastards away…”
