Nightwalkers.io is defined as a survival game which allows multiple players to enjoy at the same time.
In this game, your mission is to survive a terrible zombie apocalypse. To be specific, these walkers are filling up the streets. Therefore, what you need to do is to get rid of them while keeping yourself alive.
When you first start the game, there is no weapon expect for your fists. In this way, what you can do is punch the zombies continuously.
As players progress to later levels, they will find it easier to pick up ammunition and weapons that let you eliminate the zombies effortlessly.
On the other hand, you have to pay attention to other players. Specifically, you can find some players to form a team, fostering good collaboration in destroying the zombies.
However, you can also choose to view them as enemies. Either way, this is up to your decision.
Another thing to keep in mind is that you might find it hard to get used to this game at first because it leverages the top-down camera view. Not to mention that the noise meter can be extremely useful in some cases.
