Who Would Win?

uhhhhhhhh

sus
yes very sus

i think the impostor bc he has a ranged weapon, so he could shot him from afar

You forget AK Rifles have limited ammo, so the creeper just has to take cover to wait for a reload, it's history from there.

The impostor coud sabatoge lights, oxygen, reactor, commutications, and i think there was one more

He could run while reloading

It's unlikely, imposters don't reload or cock their pistols on the go. They constantly have to cock it for every kill they use.

Also, there is only so much ammo an imposter could conceal without looking suspicious, I'd assume only one magazine. And I would doubt that the backpack they wear contains ammo.

U know the saying abt "Don't bring a gun to a sword fight"

That is just a saying, it is unlikely that a skilled sword user has a 100% chance to lose a battle, especially with Minecraft's movement mechanics.

Or was it Don't bring a knife to a gun fight

doors

Door closing is temporary, and any lethal sabotages are impossible when the doors are closed. If the imposter went to rush the creeper with a dry magazine, the creeper could kill him with a critical hit from his sword.

Besides, a creeper could easily start a detonation sequence if the imposter got close. Even if the imposter has a maximum kill range, it would be risky without the AK realistically speaking

true dat
