Couldnt find much but stuff from 2009. But we need better animations. Like pulling the pin and throwing the grenade. This will also make the game look better and not look like a grenade getting spawned and propelled forward.
Plus i think always run shouldnt be a option. Most games you can press run and you will run for abit, tire out, walk and you can run again. This will give more realism maybe slow down the pace of the game. So it isnt as fast paced. This could also help with map making, making it easier to think about your routes.
Just came to mind thought i'd post.
