As you go along your day you are suddenly transported to the Khazan Arena. There, the CBR gods inform you that the zombie apocalypse is within days of beginning. They decide to assist you for their amusement and allow you a choice of items to aid you.
One one side you have a magical pistol. The pistol is guaranteed to never jam, has an infinite supply of ammo(meaning you can continuously shoot without needing to reload.), and does not make a sound when being fired. You are given a week of training in the arena to familiarize yourself with using the pistol.
The other choice they give you is a magical hooded cloak. When in use the cloak turns you invisible. While the cloak is being worn animals, people, and more importantly zombies are not able to see, smell, or hear you or whatever you are carrying underneath it. However you can still be accidentally touched/hurt if you're not too careful moving around.
You are telepathically connected to either item(meaning you know at all time where your particular item is.) And the items only work under your use, if anyone else attempts to use them they become immediately useless/broken. Once you have chosen, you are sent back to where you were and have 3 days to prepare.
The zombie apocalypse is upon you, which item do you choose to help you in your journey?
