here is a very early playable build.

“Ok now, stay cool, don’t panic, remember you only get one chance to hit your target, you succeed and everything will be fine, you will go back to your nice house with your girlfriend, she is here, waiting for you (cries of girl) we don’t want to hurt her, unless we are forced to, you just have to kill that guy. Remember, he’s a smart one, and he’s protected, if you miss once, there won’t be a second chance, ain’t that right honey?
