Hello, my name is Martin Oberhaus. I'm the person in charge of 2D Art at Akimbo Team Productions, the team behind Action Half-Life and the upcoming Action Unreal Tournament. They decided to try and make their own and went ahead to create Action Quake2. As mentioned above, Action was inspired by action movies. Many people complain about that because they do not understand that we are not shooting for total real-world realism.
Action is meant to be like a good action movie - fast, furious and , most importantly, fun.
AHL introduced John Woo - style stunts and dives, which were impossible to do in AQ2, as well as plenty of new weapons. I can't say what's THE most important thing. Most important is the combination of all those factors, which create an immersive action movie-like atmosphere. Well, I for one think that the current version, Beta4, is the best incarnation of Action so far. It truly is something to be proud of.
