well, this is a start. gj on making this. arma is restrictive, i'll give u that.
what i'd like to see is getting an action button when u get close 2 a small obstacle, making it possible 2 go over it (small fences, sand bags and so on). this could make you use both hands, one hand, to support ureself while doing it. but this should have the appropriate animation as well, and untill then...
gj anyway m8
