It's a good game and all but...you need to have all the upgrades related to speed to enjoy it
Reload
The guy seems to be staring at the LMG for a couple seconds to check it it's going to put the ammo on the right side
Reloading the shotgun takes almost as long as the LMG, one slug at a time so takes forever to fully reload it
Tasks
refill ammo, takes way longer than repairing your car, WHY? should be proportional to the ammount of ammo you need. Empty SMG but all others full?? too bad, you have to wait until I check if every gun is properly loaded AND polished before we can leave
Zombie resistance/gun damage
dunno, it's supposed some of the zombies are are more resistant than others to different weapons? it takes me the same ammount of bullets from a pistol to kill the weakest kind and a soldier, it takes me 2 shots from the shotgun to kill the weakest and about 3 or 5 to kill any other kind, SMG/LMG? 10+ bullets either (always aiming to the head), all of them seem to be way too resistants to bullets
I know we can upgrade everything, but the money we get is never enough and not only we have to wait until the upgrade takes it's sweet time to be done, but we need to waste ammunition while at it, in later points of the game we also pray that we won't get blasted while waiting or one or more mutants appear
