OK I have a fascination with the Zombie Horror concept, the movies and games. But after a while I began to wonder if Zombie Movies/Game/TV downplay the effectiveness of the modern military. In the UK there has been a good deal of memorial programs and media coverage regarding the first world war. As you know soldiers ended up in bogged down trench warfare where the 'no mans land' was dominated by the new technology of machine guns. Yet in the Zombie genre the effectiveness of automatic weapons, machine guns and artillery is often forgotten or skipped over as they drop you into the world without the military or government or the Zombie Apocalypse. My theory was that a platoon of modern infantry could fight a retreating action against a streets full of zombies. And with enough platoons even massive hordes could be whittled down and eradicated. Anyway I raised this as a subject on reddit and it got people thinking and talking. I got some great feedback on issues I had not considered. The fact that the military is taught to shoot centre of mass and head shots are very hard to do at range without a scoped sight. But I thought a better way to test my theory would be to build a simple simulation in Unity. So I developed 'Hold the Line' a very simple zombie horde fighting simulation. Initially I had only the players gun but that didn't match my theory so I added more weapons slaved to the players gun and 9 troops or guns firing into a street full of zombies can make quite an impact. See for yourself http://arowx.itch.io/hold-the-line Currently it uses 'paintball' style physics each bullet is a sphere that is shot and only removes a zombie when it hits the head. But what could I do to improve the simulation? And have you used Unity to simulate or test an idea?
