Greetings! I'm Tyler Jessalynn from TDGmods. I work as one of the Lead Designers, and am a big part of Hypertension. Hypertension is a commercial game which takes inspiration from an earlier game called Blood. We are currently in the progress of converting our old sprite based objects to newer lower poly models. It would entail that the modeler work with an older format known as MD2, but we also use MD3. Models would need to be keep below 4000 polys. Hope to see some responses soon!
