The weapon upgrades and creation is very neat and the combinations are not only effective but also very cool.And the creations you make shouldn't be taken lightly. If you spend money and parts on making badass weapons it's important to take care of your weapons like repairing them any chance possible and not throwing them at zombies recklessly. Every weapon in the game can be thrown, but you'll risk losing the weapon if you do.
