Block Zero

Five minutes is plenty. Drop off your starting rooftop into the infected, sprint up a building wall, then glide back over the street. That loop is a whole round, so it suits a quick break without any commitment.

Move with WASD or the arrow keys. Sprint straight into a building to run up its wall, hold jump to glide across the street, and press dash in mid-air to change direction. Then land wherever you fancy. It all clicks within a minute or two.

Yes, and it's the whole trick. Sprint into any building and your blocky mutant runs straight up the wall. Every wall is a road to the roof, and every roof works as a launch pad for your next glide across the street.

You're a blocky mutant born of the outbreak, loose in an open low-poly city. You're not hiding from the infected crowd. You jump off a rooftop right into it, fight through, and use your gliding and dashing to stay mobile.

The city has three zones. There are quiet residential blocks, a quarantine packed with infected, and a corporate base up north. Each one gives you rooftops to leap from and streets to glide over, so you can roam freely.

Both. The city is open, so you can wander and climb as you like. Resistance terminals also hand out short missions, which give you something to aim for while you fight through the infected-filled streets.

Yes, it's a one-player game. You're the only mutant on the rooftops, so there's no lobby to wait in and no team to coordinate. Press Play, jump off your starting roof, and you're in the action.

It's free and runs right in your browser, with no download. It's built for desktop play in landscape view, using the keyboard. Open the page, press Play, and you're dropping onto the first rooftop within seconds.
