Nightpoint.io is a panicked multiplayer shooter where you have to fight in a 2D city landscape against hordes of undead zombies. The graphics are reminiscent of Pokemon games and you can choose from several different 2D characters. To begin with you are equipped with a gun but as you level up you can choose different weapons including machine guns, shotguns, and flame throwers.
You have to move around the city and survive as long as possible against zombies - they respawn from time to time so there is always a threat - you can never guard your defenses. Next, zombies will be pulled towards you so you have to keep moving and shooting. As you level up, you can increase your character's stats such as speed of movement, health, and health regeneration - this will help you last longer. You also have to consider other players.
