1.Sure, the lean and peek mechanic already exist so I see no issue with crouching
2.Zombie pheromones already exists so I see no point but maybe the devs may wish for this…
3.Erm maybe I don’t know about this as it would basically be the crawling benefit stated earlier only without the aim benefit while increasing time taken per move
4.Sure, they exist in reality but I believe this would only affect animals as zombies basically just approach anything that smells vaguely alive
5.Despite breaking bad Thermite doesn’t melt most locks aside from poorly made aluminum padlocks https://www.youtube.com/watch?v=5dJww7TcpX8, personal tests and most pyromaniacs will tell you similar
6.Sure but it would take around a hour to cut most padlocks but you could also heat the locking mechanism with the blowtorch to hope the hook mechanism expands to the point of releasing the lock, however on anything that isn’t a padlock this would be beyond a chore
7.I would actually like for this to be a system but it is a bit too awkward to code given the current leveling system that exists although most handguns/modern rifles aim in a similar fashion with iron sights, the only thing that change should be reload time and recoil adjustment on guns you are not trained within so I suppose the current system is better
8.Sure
9.They are very rare but why not
