As you can see, many types of games are available, including action games, arcade games, card games, puzzles, role playing games, and strategy games Some Linux games can be played from the console; others require X Many Linux games let multiple players compete at separate computers connected via a network, such as the Internet Linux games may be freeware,

shareware, or commercial software In addition, Linux software such as Snes9X and WINE lets you play games originally written for systems other than Linux

9.2 Closeups of Some Popular Games

In this section, you'll get acquainted with three popular games you can run under Linux:

 DOOM, which runs on a console or under X

 Quake II, which runs on a console or under X

 StarCraft, which runs under X by using WINE

9.2.1 DOOM

Originally written for MS-DOS by id Software (

http://www.idsoftware.com/), DOOM is the archetypal 3D action game You play the role of a space marine, fighting your way through a series of bases

on the moons of Mars that have been invaded by aliens The game features real-time 3D graphics and stereo sound effects Figure 9.1 shows a typical game screen

Figure 9.1: A typical DOOM screen

If you prefer more cunning opponents, you can play the game in network mode, via modem, or an IPX or TCP/IP network Network mode lets you match wits with two to four human opponents

To run DOOM in a console, type the following command:

sdoom -warp 1 1

If you prefer to run DOOM under X, type the following command:

xdoom -warp 1 1

To call up DOOM's main menu, simply press Esc

You can learn more about DOOM by visiting the DOOM Archives at

http://www.idsoftware.com/archives/doomarc.html and the Linux DOOM FAQ at http://jcomm.uoregon.edu/~stevev/Linux-DOOM-FAQ.html You might also enjoy lxDoom, a Linux port of Boom, which is an enhanced version of DOOM

9.2.2 Quake II

Like DOOM, Quake II was also written by id Software However, Quake II

is a much more modern and sophisticated program than DOOM For

example, Quake II's multi-player mode lets as many as 32 players wander the planet of Stroggos And, the single-player mode pits you against 18 artificially intelligent adversaries, who dodge your careless shots with agile ease Figure 9.2 shows a typical Quake II game screen

Figure 9.2: A typical Quake II screen

To run Quake II under X, change the working directory to the directory in which you installed Quake II, and issue the command:

./quake2 +set vid_ref softx

To run Quake II using a virtual console, issue the command:

./quake2 +set vid_ref soft

Once the game is running, you can access its main menu by pressing Esc 9.2.3 Starcraft

Starcraft is a real-time strategy game published by Blizzard Entertainment,

in which you participate as the leader of a group of humans exiled at the edge of galactic space Your objective is to assemble a military force capable

of dominating two other species, the Protoss and the Zreg To do so, you must build bases, vehicles, and weapons, and train soldiers for combat

Starcraft was not written for Linux; however, you can run it under Linux by using WINE Assuming that you have WINE installed on your system, the following sections explain how to install and run Starcraft:

9.2.3.1 Installing Starcraft

If you have the commercial version of Starcraft, mount the CD-ROM

diskette and locate the file install.exe If you want to try the Starcraft demo, download the file scdemo.exe, which is a little over 28 MB in size You can

find the file on Blizzard's Web site ( http://www.blizzard.com/) and

elsewhere

Change the current directory to the directory containing install.exe or

scdemo.exe and use WINE to install Starcraft:

wine -display localhost:0 -winver win95 scdemo.exe

When asked if you want to install DirectX 5, highlight the No, But Continue option and click on OK Choose the directory in which you want to install Starcraft (the default choice is generally acceptable) and click on OK If the program asks if you want to register via the Internet, respond by clicking on

No Finally, click on Exit to terminate the install program

Under Linux, Starcraft operates in 256-color 640�480 mode Therefore, you must adjust your X configuration to provide this mode Here's a quick

way to do that First copy the file /etc/X11/XF86Config by issuing the

following commands:

cd /etc/X11

cp XF86Config XF86Config.SAVE

cp XF86Config XF86Config.StarCraft

Now, edit the file XF86Config.StarCraft using the editor of your choice

Find the "Screen" section that specifies the X server (driver) you use and change the Depth parameter to 8 and the Modes parameter to "640x480" Delete any additional modes that appear When you're done, the screen section should resemble the following:

Section "Screen"

Driver "svga"

Device "Millennium"

Monitor "Viewsonic17GS"

Subsection "Display"

Depth 8

Modes "640x480"

ViewPort 0 0

Virtual 640 480

EndSubsection

EndSection

9.2.3.2 Playing Starcraft

To play Starcraft, replace your XF86Config file with the newly edited one:

cp XF86Config.StarCraft XF86Config

Then start X:

startx

Launch an X terminal, make the Starcraft installation directory the current directory, and start the Starcraft program:

#

cd "/c/Program Files/Starcraft Shareware(ED)"

#

wine -display localhost:0 -winver win95 -depth 8 \

>

-geom 640x480 Starcraft.exe

If you installed Starcraft to a directory other than /c/Program Files/Starcraft

Shareware(ED), you should adjust the commands accordingly

Now, play Starcraft until you completely dominate the galaxy The tutorial mission will help you learn how to do so Of course, planning and executing

a winning strategy will require practice

9.2.3.3 Ending a Starcraft session

When you're done, press F10 to obtain a game menu, exit the current

mission, and exit the game Then, replace your original XF86Config file by

entering the commands:

cd /etc/X11

cp XF86Config.SAVE XF86Config
