Best Open Source Top-Down Space Shooter : Super Space Invader

Lasers, rockets, shields, health regeneration, pixels. You know. The good stuff. Just nicely packaged with levels of just the right duration and hardness, persistent upgrades, shaders, reverb...

Two buttons are enough to play, since that was one of the themes of Ludum Dare #34, in which the game came #74 among 1638 jam entries.

Super Space Invader Review

Supser Space Invader was made with LÖVE (v0.9) and thus runs on Linux, OS X, Windows.

The source is available on GitHub under zlib/libpng.

Galaxy Forces: Moon Lander Action!

Galaxy Forces is an open-source moon lander shooter single-/multiplayer game hosted on SourceForge, it is nearly finished.

It is unique of its kind in offering global hiscores and achievements. Replays and AI enemies also available.

Try it. It plays on Win, Mac and Linux.

Strife: Veteran Edition

Just in case you can stand having Steam DRM installed in your system, I recommend taking a look at Strife: Veteran Edition. Strife is a Shooter/RPG based on the Doom Engine and dating back to 1996. The developers for this new remake had the wits and sensibility to use the Chocolate Doom engine as the main code base, which is, of course 100% licensed under the GPL. With so many top quality Free Software engine remakes around here, it really astounds me why so few developers choose to use them on modern HD remakes and ports (I'm looking at YOU, upcoming remake of Heroes of Might and Magic III not using VCMI).

As mentioned, so far the game is available exclusively on Steam, but I'm pretty sure a DRM-free GOG version will eventually follow, as it usually does.

Winter Shorts 1: Word War Vi Laser Edition, Space Nerds in Space

SNiS Engineering screen

Stephen Cameron, one of my personal heroes of game development (Be The Wumpus), made Word War Vi support color laser projectors using the openlase library [blog post].

Another project that our forum users were allowed to follow in this thread is Space Nerds in Space:

So this game (when it becomes a game) is very much inspired by Artemis Spaceship Bridge Simulator
See: artemis.eochu.com The idea is you have a game which is played much as the actors in the Star Trek TV series played their roles on the bridge of the Starship Enterprise. There are a number of "stations": Navigation, Weapons, Science, Communications, etc. and each player assumes that role. Each station has it's own laptop or other computer which communicates via network to a central server which simulates the game universe. So it's kind of a cooperative multiplayer network game... No reason not to have multiple teams in multiple starships inhabiting the same server/universe either cooperating or doing battle.
Mine is different than Artemis Spaceship Bridge Simulator in that it is:
GPL'ed.
Linux/gtk
Probably uglier (lol).
Probably more scalable (yay vector graphics.)
Not even close to finished.

It will probably be a while until I'm in a room with enough Linux users to test play this game but when the time comes, I shall be prepared!

Onslaught Arena Now Open Source Code!

Onslaught Arena

Onslaught Arena, a HTML5 top-down shooter that has a non-space-ship-scenario, is now open source code, non-free assets on GitHub.

video: Onslaught! Arena: How to beat the Green Dragon

The assets are included under non-commercial terms and the developers did not have the time to read about Creative Commons licenses, which I'm sure is one of the reasons why CC-BY-SA isn't widely adopted: time. If you are able to give a concise description, please do in this thread.

The team's blog is also home to a podcast about HTML5 games.

Coldest: Mech AI and Playtesting with the Dev!

Bots were added to the mech fighting game Coldest. If you would like to help playtest the game together with the developer, follow the project's news feed (there will be an announcement for a session sometime soon) and get the git version via:

git clone git://coldestgame.git.sourceforge.net/gitroot/coldestgame/coldestgame coldest

Mass Blaster: Ambidextrous Abstract Shooter

Synchronized shooting in Mass Blaster

Mass Blaster is one of the most intense arcade shooters for Windows and Linux. You will take control of two ships simultaneously to blast away at the invading Square Army. On your left, take down enemies with the red n' rad Trigerus. On your right, command the cool blue Pythagora to wipe out your foes. Choose from 4 modes of difficulty to fight your way through 10 gutsy levels. Only those with the skills to pilot both ships at the same time will go on to become High Score Heroes.

This game shares a vein with games like Avoision and pumps adrenaline. Intended for one player, Mass Blaster plays superb with two pilots as well. Just get a keyboard emulator and a joystick to avoid key locking.

Code is under GPL, while all other assets are under the not-so-free CC-BY-NC.

HTML5 Defense: MiniMek Urbie Defense

Two 'towers' down in MiniMek Urbie Defense

A little top-down defense game was released under GPL (art & code) as a new year's present. It shows nicely, how libre art can be used for small game programming projects.

These use some art assets from megamek (http://megamek.info/) and therefore these games are also licensed under the GPL 

A straightforward interpretation of the GPL applied to assets. I'm afraid though, the images of MegaMek might be incompatible with the GPL, due to Battletech copyright and/or trademark.

The game has good performance but little complexity except for a Missile Commander-esque twist: getting hit reduces player's spacial ability to shoot.

According to the project page, more games with the same graphical theme are to be expected. I'm looking forward to them!

GunFu Deadlands 1.01: Performance Up!

GunFu Deadlands title screen

GunFu Deadlands, a quick, atmospheric retro keys+mouse top-down shooter for Win/Osx/Lin has been updated (1.01) to run with LÖVE 0.7.2 and the development codebase moved from Subversion to Git.

The game plays perfectly fine on a ASUS EeePC 1000H netbook running Arch Linux 32bit. A previous version (don't remember which) was extremely slowly. I can't tell whether the playable speed is thanks to improvements of GFD, love2d or perhaps the drivers for my netbook but if you've had performance trouble with the game in the past, try again!

Note: if you get shot in the title screen and start the game before respawning, you will be able to walk through walls.

This is the first update of GunFu Deadlands since the 1.0 release 22 months ago.

Video: GunFu Deadlands 1.01 gameplay

By the way, did you know that GunFu Deadlands is one of the 250 Indie Games You Must Play?

PS: I got word from the developer about the performance increase:

Just for your interest, I made some measurements and it seems that the speed increase is indeed dramatic: 55% faster.

I computed the mean FPS rate by measuring the time it takes to render 1000 frames in-game and dividing 1000 by this number. The formula (FPS_faster_version - FPS_slower_version) / FPS_slower_version is what produced this 55%.

The PyWeek guys seem to have figured out the license part of game prototyping well: Lemming for example contains a list of all used art pieces' urls and licenses. Neat!


PS: Ludum Dare got 600-1 entries last weekend.

LinWarrior r19+

LinWarrior r19+ Test Video

I tested and recorded the latest LinWarrior git revision (a few changes since release19). Some of the new features in r19 and after include:

• Atmospheric daytime setting
• New units (Flopsy, Scorpion and Tank)
• Cockpit frame in first-person view
• Trees, trees, trees

The LinWarrior engine is still being developed, for example mechs are still hardcoded rather than configured in textfiles right now.

PS: A video of actual gameplay, rather than just testing the controls. Unfortunately no sound but 1920x1200 resolution...
