It would be nice to have a little tournament and get to know people better here, though saddly I dont have the time, patience or money to run a server.
On the subject of critical hits, critical hits dont happen when u hit someone in a certain area (although this happens when u snipe someone in the head; this is the only example of this being true) critical hits happen before you shoot, so you can still technically miss with the actual critical hit. Ive heard many rumors as to how often the critical hits appear, ranging from how many hits you strike on opponents before dying, how many kills you get before dieing, or your overall performance so far... Im not really sure what the truth is :\.
Also an interesting thing I learned from the steam forums is that there is no laction oriented damage in this game with shots. (except for the sniper rifle, and knife i guess technically) What I mean is, if you shoot someone in the head with the shotgun, it is no different than shooting that person in the foot. Although, the damage variation comes from your distance to the target, as well as how much of the whole shot hit him. (like with the shotgun for example, although i dont know if this is true) Another thing Ive found out is that rockets have been modified to be like a shotgun; if u get hit with a rocket from far away it does less damage than it would from close up. Also from my experience, ive noticed a direct rocket hit seems to do more damage, more or less kill you instantly then a rocket shot at your feet. (though i guess thats obvious why and goes without saying)
