I joined the sabre fencing club in my sophomore year of college. It was a small operation, but a lot of fun, and there were lots of stories our coach, Dom, told us from his fencing club back home. One of them goes like this:
He was losing a bout, and so asked his coach what to do. His coach, who he called Chris, said something to the effect of, "Well, you know, the only two parries in sabre are duck parry 5 and jump parry 2 ." Chris was referring to a mind game where you can duck down, and guard your head on one turn and on the next turn, jump as high as you can (without crossing your feet) and guard your torso, since your opponent would expect your torso to be unprotected. The combination of these moves allowed Dom to throw his opponent off their rhythm and regain control of the situation, though honestly, I don't remember if he won.
The idea this story gave me was, "what if Chris wasn't joking, and those really were the only two parries in sabre?" Therefore, the concept is a fighting game where each player has two attacks (head or dominant side torso), and two parries (jump and do a parry 2, which guards your dominant side torso, or duck and do a parry 5, which guards your head).
The game will be made in Unity, with models made in Blender.
