KRaptor a Raptor free software (open source) arcade game clone for GNU / Linux

Monday, January 30th, 2012

Kraptor is another Raptor Shadow of Death free software, open source clone arcade game for GNU/Linux, DOS and Windows (98, XP etc.).

The game is not under active development anymore since 2004. Kraptor features a powerful engine for creating quickly 2D shooter games, so the game should be a good learning curve for people interested into creation of arcade game shooter games.

The game just like Rafkill is built upon DUMB sound engine.
The game intro is quite entertaining ;) The intro plays one by one the text:

Near Future:
Blobalization
Imperalizm
Corporations
Megalomaniacs
Money and Power. Slaves of the New Millenium!

KRaptor Bill gates like looking oppressor

After years of oppression, the slaved people of the world have raised against their masters. You, has a mercenary pilot, has been
contacted by the popular rebellion to fight against the forces of oppression.

In the morning, you jump into your cockpit and start up the engines. It's time to get airborne and start the attack. Get ready to
scramble the scum hired by the masters. Murder for freedom is the only way, you're on a mission, don't defraud us...

Like Rafkill, Kraptor is one man masterpiece created by a free software Argentinean geek known under the Kronoman artistic pseudonim. The game is really incredible for a one man work … a true masterpiece.
The game is licensed under MIT License.

Even though Kraptor is older game than Rafkill, the design is more resembling the original Raptor game. The game music is high quality stereo. Besides that music and fx sound effects are quite awesome. After each level you have a Raptor like weapons "blackmarket", where you can buy new weapons, recharge ship energy, upgrade ship etc.
The blackmarket implementation part of the game is probably the worst moment in the game along with the game menus (in my view).
Talking about graphics Kraptor supports really high number of resolutions ranging from 320×240 to 1280×1024! 640×480 is the standard resolution in which the game is running.

Something I really like in the game is the number of multiple weapons your ship uses during play. Even if played in Easy mode it is taught.

There are game Saves after each level, so thanksfully you don't have to start again from zero once death.
At the end of each level there is a huge bad BOSS you have to destroy ;).

Installing Kraptor on Debian / Ubuntu and deb derivatives is with:

debian:~# apt-get install kraptor

On most rpm based Linux distributions, you can install the game by converting the deb package to rpm with alien or by building from source from Kraptor's sourceforge page

Its interesting the game name e.g. Kraptor is also a death / grind metal band name, (Maybe Kronoman is metalhead big fan of Kraptor and that's how he came up with the playful name. For all the old school game addicts there is the joystick support. I've tested it with my Genius analogous joystick and it works fine.

The game is lacking .desktop gnome definition and after once installed it only appears through Debian (section) GNOME menus and not in Applications -> Games :

Applications -> Debian -> Games -&act; Action -&t; Kraptor

Just like Rafkill on Debian the game exacutable binary is located in /usr/games/kraptor . Also like with the Rafkill case when launched the game has troubles with choppy sound and music caused by the stupid buggy! pulseaudio

Analogously like with Rafkill's case, the work around to the problematic music en sound is to use a little bash shell script like:

#!/bin/bash
pulseaudio -k;
/usr/games/kraptor
pulseaudio --start;

You can dowload Kraptor fix sound issues wrapper here

To install it on your Debian / Ubuntu and hence make the game sound play good issue with root:

debian:~# cd /usr/bin
debian:/usr/bin# wget http://www.pc-freak.net/bshscr/kraptor.wrapper.sh
...
debian:/usr/bin:# chmod +x kraptor.wrapper.sh
debian:/usr/bin:# mv kraptor.wrapper.sh kraptor
