One Chance

One Chance is an adventure story game that puts you in the shoes of scientist John Pilgrim, whose breakthrough cure for cancer has triggered a global catastrophe. In just six days, a deadly virus will wipe out all life on Earth. Each day, you have the same question to answer. Will you spend time with your family, go to the office to find a cure, or take a third option? You only get one shot, so aim to make the right decisions. The Universe depends on it.

What Is One Chance?

One Chance is a classic Flash-era browser game, from Awkward Silence Games. You can play it free in your browser here — no Adobe Flash Player required.

How to Play

Press the Play button on this page and One Chance loads directly in your browser — free, with nothing to install.

Each day, you decide how John spends the last six days on Earth, either frantically working for a cure, spending time with family, or getting tempted by other options like playing hooky from work with colleagues. Your choices lead to one of several endings, and you only get one playthrough unless you restart in incognito mode. That is the thrill of the game! It is literally one chance.

Note: The following sequence follows just one possible path through One Chance. The events, scenes, and endings you encounter will vary based on the choices you make. Your sequence of days may unfold differently, and some moments described here might not appear in your playthrough.

Controls

Here's what each control does:

• Left and right arrow keys = move - Space = interact

Day 1

You wake in your bedroom. Penny, your wife, reminds you that today is the big day. On the way to work, you read in the newspaper that cancer has been cured. At the lab, colleagues congratulate you for developing E48 K15, a breakthrough treatment already approved for global distribution. The world celebrates.

You can go to work or skip it; your choice sets the tone for the days ahead.

Day 2

The next morning, the paper’s headline changes everything: “CURE DEADLY - Destroys All Living Cells.” The E48 K15 kills not only cancer but all living tissue, and it spreads rapidly, killing plants, animals, and humans. Panic quickly sets in.

Depending on the root you take, stay at work, one colleague takes their own life in despair. You must choose, do you keep working or walk away?
