another idea for the pistol....a silencer and maybe a secondary pistol that adds an infinate ammo but is lower damage and overheats fast....maybe im thinking too hard or asking two much but some weapon slots could have more then one slots posably...another idea and this is a small one is add your own beastiary for demons items guns and so onto have info in game about things but ofcorse after aquireing data on  them in a level outside the test level this will let you better explain alt fire modes and what the ammo is to add alittle info without having to do too much work other then adding a new thing in the main menu and unlockables for said new menu though daisy the pistol and kick should be already unlocked naturaly seeing its default stuff...id also debate armor and health shards being explained and maybe the armor pickups but now the temp power ups to encure more exploration and curiocity to those that havent played doom before<if such a person exsists>
