Together We Defend, A Cooperative Crowd Game Prototype

I’ve made prototypes for local multiplayer games with 10+ people before – some very successfully, some less so, but always with great pleasure. There is something magical about a crowd of people all playing the same game together. You don’t just need to design good mechanics though – the game should balance well with a few or with a lot of people, which is also hard to test because you always need a crowd. Another problem is input: While yelling with varying volume in Screamy Bird is tremendously fun, it is a bit limited control-wise. Unless your crowd is very small, giving everyone a gamepad is not an option. But these days, most people have a smartphone with a web browser, and luckily, platforms like AirConsole and HappyFunTimes make using these as controllers extremly easy!

My goal was to make a game where people have to cooperate and that scales well with different amounts of players. To ensure cooperation, the game would feature two radically asymmetric roles: the Shooter, which can attack but dies to a single hit, and the Defender, which has no offensive capabilities, but whose shield can absorb any amount of damage. In the center of the games are the Cores which the players have to defend. Enemies come in from all around the screen and try to destroy the players and the Cores, whatever is nearest. The enemies’ projectiles are heat-seeking – they will always hit something, so without the Defenders, the Core and the Shooters will be destroyed rather sooner than later; but without the Shooters, the defenders could not destroy a single enemy.

This was a jam game done in about 12 hours and everyone around me was busy, so I there was no way I could balance it properly. I solved that dilemma by assuming the role of the game master: I would sit at the keyboard and spawn enemies.

Apart from troublesome connection problems, the game worked rather well for a jam game and the crowd loved it. Here is a video of the presentation:

Together We Defend, A Cooperative Crowd Game Prototype

The video was filmed by Iwan Gabovitch and the sound effects are from the fabulous Universal Sound Effects which I can very much recommend.

Connection problems aside, I am very content with how the mechanics worked out and I think there is a lot of potential there. I will probably revisit this prototype some day and make a proper game out of it.

Starship Command Center Pro, The Trial Version of a Global Game Jam 2015 Game

Somewhere in space, a lone starship discovers that the theme for this year’s Global Game Jam was “What do we do now?”. It also discovers that a very cool game was made for three players. And that there something is wrong with its Operating System.

Deep in space, nobody hears you scream
when the trial version of your OS runs out.

Not that screaming would do much.
Instead, you and your two friends now need to
figure out what the randomized buttons of the
free version of your system do.

Together, operate thrusters, cannons,
shields and a mining magnet, collect
gold and buy a proper license!

The theme is used twice in our game – once in the game mechanic with players having to talk to each other what do to next because they need to work together, and secondly in the story: The trial version of our control system has ended and the result is a chaotic and unknown button layout, what do we do now?

We even satisfied a diversifier (sort of an achievements for the developers) this time: Noise Generator, “The mechanic of the game is based on players having to stay in constant communication with each other.”

Fun fact: Originally we wanted to do the controls Spaceteam-like with custom controls on multiple smartphones – buttons, sliders, rotatable knobs. It took us over a day to get it to connect and run smoothly between Android and PC, only to find out that using controls on a touch screen while looking at another monitor felt awful and (apart from buttons) was nearly unusable. So after that day of work, around 5 in the morning, I spent 30 minutes to program replacement gamepad controls. It worked perfectly and felt good.

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.

Screamy Bird, A Yelling Game Prototype For A Small Crowd

It seems like everyone and their dog has made a Flappy Bird clone by now, but so far I just didn’t feel inspired. That changed at this Mini Game Jam: I wanted to make a game with audio control (which I had tried before) and needed simple gameplay for it – and then I realized that a scrolling avoider-type would fit perfectly. So without further ado, this is how Flappy Bird might have played like if it was made by the GNILLEY developer:

I don’t know where people could possibly play this game without bothering anybody, but it was a big success fun-wise and was well received in the presentations. My favourite part is that it’s easily playable with crowds!

(And it would probably be perfect on smartphones, haha.)

Massive Defense: A Cooperative Game for 27″ Touchscreens and Android Tablets

Game Jam time! And when I saw Heiko with this beauty of a touchscreen, I knew that I had develop for this. We wanted to do something where players can cooperate against a common thread. 8 hours later, we had this:

Massive Defense

An asteroid storm threatens your mission,
but your trusty spaceships stand ready.

Defend your home base!
Defend your friends!

Try to survive as long as possible in this
cooperative asteroid defense game for 4 players.

Exclusively for 27″ touchscreens!
(Or alternatively for 4 XBox360 gamepads.)

While it’s certainly possible to play on a tinier touchscreen, playing it on 27″ was a lot of fun! Here’s a video of us playing it at the jam:

Blood Trial (Alpha Release)

The theme for the Global Game Jam 2013 was the sound of a heartbeat. After briefly pondering making a game about friendship, love and the joys of life, our thoughts drifted off a bit and we made something, uh, a little bit different. Enter Blood Trial.

Blood Trial (Alpha Release)

You are participating in an
ancient ritual to appease the blood god.

Rip out other warriors hearts and sacrifice them
at the top of the temple while they’re still beating!

Keep the favor of the thirsty god and he’ll reward you generously!

The Great Hunt: A Massively Multiplayer Offline game prototype for up to 10 players

June Berlin Mini Game Jam. The theme is “hunting”. My secret theme is “Massively Multiplayer Offline Game”. One man, one mission, 8 hours to go!

8 hours (plus 3 hours bugfixing) later I’ve got this:

The Great Hunt

Enough with the monsters killing off the villagers!
You are a brave hunter, and you’re getting paid to deal with these pests!

Well, you’re not the only one hired though. And only the best will get paid.

Be the last man standing, or at least finish first with 60 points!

Play here, as always directly in your browser!

 

While the game is playable and actually features up to 10 players (on 4 keyboards, no less), it fails in many other ways.

The basic idea behind the game was “Too many cooks spoil the broth.”: You need other players help to take down monsters, but the more players participate the less points you get. So when you’re standing in front of a monster with others players beside you, you’d be like “Dude, back off, if you stay here we won’t get much points anyway!”, or maybe you’d switch last second to another monster.

So much for the theory. In reality everything goes down so fast (and is so chaotic) that there isn’t much communciation or tactics. Fights also take too long and are not balanced, and there are not much real choices.

I have to admit that I’m not sure how I’d fix the game without introducing more complexity like power-ups. Anyways: It was a fun experiment, and lessons were learned. (The main lesson being that 10+ people games are possible in 8h. I guess I’ll never learn, haha. Looking forward to next jam!)

Global Game Jam 2010, or: Zino Zini

This post is the continuation of Global Game Jam 2010, or: We don’t make games, we make AWESOME games (in 48 hours).

The Game

Our final game is about obtaining as many bubbles as you can! You can do this by just peacefully collecting them, as there are many, but soon there won’t be – and then you have to dash at other players and hit them so they drop their bubbles and you (and everyone else, hurry!) can collect them. An interesting (and deceptive) mechanic is that you can go off-screen so that you don’t show, and while hidden, wander, so you deceive players about your real position – and suddenly jump out and get them! Furthermore, you can teleport a few times to the other part of the screen, and doing this while being hidden outside of the screen is a good method to sneak up on the others! (If you have read the post before: There are no alliances anymore, and there is only one kind of ball to collect.)

So without further ado, here is it: http://www.globalgamejam.org/2010/zinozini

I suggest you download the version in the “Installation Notes” below, because there are a few bugs fixed – but well, we won’t take down our 48h-state, it is also highly playable. :)

Your graphics card needs to support Shader 3.0 to play this game, and it is optimized to be played with Xbox 360 controllers. If you don’t have them, download it anyway, it even makes fun without them!

The game is written in C#, with XNA as framework.

Oh, and by the way, here is a Zino Zini wallpaper:

The Team

And here’s our team again, for those of you who skipped the other way-too-lengthy post:

Lars Kokemohr – Programming
Me, Tobias Wehrum – Programming
Daniel Bock – Game Design and Music/Sound
Norbert Haacks – Game Design
Additionally featuring: Phillip Gronek – Q&A Tester, Fun, Red Bull

What will be added soon

  • A score screen!
  • A test for Shader 2.0 (yes, 2.0. We want to make it run on 2.0, so stay tuned if you don’t support 3.0!)

Actually, we wanted to add a bunch of other stuff, for example but not limited to: A Splash Start Screen showing our splendid logo (om.nomnom games), a start menu, a credits page, preferences (sound/music on/off), a different mode without time limit, and and and… but time ran out, and since it is playable in the current state, we will only add the things named above for sure.

PS: If you ask where there key, the monkey or the donkey is, well… that is a riddle, wrapped in a mystery, inside an enigma, and therefore hard to find. (There is none. It got lost somewhere along the way of the development process, and afterwards we felt the game is too much fun to try to press a constraint in there. Earlier the balls collecting the bubbles should’ve become monkeys, but that wouldn’t go with the fine abstract look it has now.)
