A Light in the Darkness – Co-Op Online Multiplayer Game Made in ~52 hours

A few weeks ago, I participated in the Ludum Dare 30. The theme was “Connected Worlds”, and I thought “Hey, nevermind that I never made an online multiplayer game before, I should totally try to make one in 48 hours!” Unexpectedly, it actually turned out pretty great – you can read more about that in my postmortem if you’d like to. And below you can find the ~52 hour post-compo version with a few bugfixes and sound effects!

You are flame bearers, braving the darkness,
carrying letters and escorting travellers
through the eternal darkness between
the mountains to the south and
the sea kingdom to the north.

Overcome obstacles. Carry the torch on. Work together.

Go north. Ignore sounds in the dark.

And most importantly: Don’t let the flame die.

Here is a video with clips of lots of people playing it on dvcolgan’s stream:

…but first invite a friend or two. It’s dangerous to go alone!

The rating period is slowly but surely nearing its end, and I thought it cannot hurt to write a postmortem for the game I made three weeks ago. I wish I would’ve promoted the game more (it’s my first online multiplayer game after all!) and I wish I could’ve played more games, but my master’s thesis was jealous and demanded I spent more time with it. That being said, I have a free minute now, so here goes nothing!

Together We Will Survive: A Cooperative Game For Two Players With Red/Red And Cyan/Cyan Glasses

A week ago, we had our February Mini Game Jam. One of the themes was “local multiplayer”, which perfectly fit the idea that I already had before arriving at the jam: Cutting up some anaglyph glasses to make red/red and cyan/cyan glasses and then make a multiplayer game where each player can only see half of the content.

Shoot all monsters of your color. Don’t let them touch you.
Your friend does the same.

Easy enough so far? Good.
Because you’ll also wear glasses in your color,
which means you can’t see your enemies at all!

A cooperative game about focus, teamwork, communication and fast reflexes –
for two players with red/red and cyan/cyan glasses and XBox360 controllers.

Also, have some videos about how it works:

Together We Will Survive (Red Glasses)

So – how does it work?

…surprisingly well! No really. But if you really don’t want to watch the first video, here’s how:

The yellow player fights the yellow monsters – he can’t interact with blue at all.

He wears red/red glasses though, and can’t see yellow at all…

…but if the blue player points his beam at one of the yellow monsters, the beam is BEHIND the monster, so it looks like this:

And now the yellow players knows where the monster is and can shoot it! All that remains now is good communication between the players and fast reflexes.

If you want to see it in action, you can watch this video.

The red/red and cyan/cyan glasses worked surprisingly well in extinguishing every single trace of yellow and cyan respectively, even in a projected image! (And in case you’re wondering, red images didn’t work, there were still faint ghost images.)

I really like how the game plays out. It’s interesting to see how people grow increasingly accustomed to playing it. Most start not talking at all and die a lot. Others focus solely on identifying the monsters for their partner and then die because they didn’t shoot their own enemies. Then, slowly, they start talking to each other: “There’s a monster here!”, “One there.”, “Move left! Left! Okay, you got it.” And later on some well-rehearsed teams start playing silently again for the most part, quickly finding the enemies their partner is pointing at.

I might visit the colored glasses mechanics again at a later jam.
