Southernmost Combine is an alternate epilogue to Half Life 2 Episode 2, in which Gordon Freeman is sent back in time to the 1980´s to stop a Combine recon deployment happening in the southernmost land of the world. There are a few deviations in gameplay mechanics (more tactical and slow paced, no gravity gun, inventory) but it´s still Gordon fighting the combine and rebels helping him to achieve it. This is a small episode consisting of a variated set of scenaries with unique art made ex-profeso to bring Source to the look of the southamerican region in the 1980´s.
Just the ones i remembered to take a shot too. There are tons of those.
You should replace the AR2 with something much older. The Fara 83 En.wikipedia.org or the FN FAL were weapons used by Argentina in the 1980's
Thanks for the suggestion. I want indeed to use weapons from the era. but the AR2 will stay because combine still have all their top notch technology. I´m using a sort of AK47 in replacement of the SMG, I´d go with the model you suggested if i knew how to create a weapon. I can model it, but i have very little experience in animating and rigging models. And I´m the only developer here.
