Off Limits (mod)
Off Limits will be a team-based multiplayer Half-Life 2 modification. The gameplay will revolve around two teams attempting to take out a small, aggressive, player-controlled alien. The vanguard team will start the round with the only gun that can harm the alien, the rogues team will see the alien's position on their radar. The team that kills the alien, wins the round.
Story
It started out with a few sightings in unpopulated regions. The tabloids were the first to catch on and spoke of a new species, ridiculed by the scientific world. But as quick snapshots turned into irrefutable evidence, sightings increased, and some were even spotted in our largest cities, both science and the military got involved. Mankind's fear of the unknown soon led to conflicts. That’s when we found out: they were invulnerable.
They were few, and they were unintelligent. But no weapons known to man at that time could harm them. They only attacked when in danger and were uncoordinated, but human nature took care of the rest. For six long years, we threw everything we had at them. No conventional weapons, no biological, chemical or nuclear weapons seemed to have any effect, other than the utter destruction of our world as we knew it. For six years, all humanity’s effort was aimed at researching new weapons to meet it’s slow but irreversible demise. At long last, chance seemed to be on our side for once. In our darkest hour, rail weaponry was our savior, and the first kill was cause for world-wide celebration.
Now, twenty-three years after the invasion, the balance is critical. We know now who and what they are. Based on the detection of several large objects in orbit, combined with the low intelligence of our nemesis, we believe they are no more than a weapon, set loose on our world by a more intelligent alien race. Their sole purpose is cleansing our planet of the parasite called man. But we won’t go down without a fight. A few dozen of them are left, though not too many of us either.
Rail weapons turned out to be expensive and rare, and only a handful of them are still operational. These are in the hands of trained containment teams, who penetrate the areas in which the aliens reside, areas off limits to all with a desire to live. There are those, however, who covet the rare railguns and their inherent power to decide who lives and who dies. These rogues will go to any length to take out the containment teams and thus betray their own race. Only time now will tell if humanity’s own greed and tendency to self-destruction will finally prove the end of our race…
