@Mactetra - The last model and the first are from the original half life but the third is an all new creature, and sadly, since the game is technically gonna be a mod, were using the actual models made by Valve that were used in HL2, but I have always wanted to model a strider so you may see that someday.
@thecolclough - which one scared you the most?
@Darkjesture - this game is going to be the sequel to half life opposing force so its basically the complete opposite of the storyline from half life 1. but it will be extremely similar to half life game play though.
and if you haven't played HL: Opposing force, basically, your a corporal in an army who were sent to kill Gordan freeman but failed and you were left behind and you had to escape Black Mesa. basically read the whole story of this game here -
