Free fps game software for linux

Tremulous for Quake 3 Arena is an open source modification that blends a team based FPS with elements of an RTS. Players can choose from 2 unique races, aliens and humans. Players on both teams are able to build working structures in-game like an RTS.
These structures provide many functions, the most important being spawning. The designated builders must ensure there are spawn structures or other players will not be able to rejoin the game after death. Other structures provide automated base defense (to some degree), healing functions and much more...
Player advancement is different depending on which team you are on. As a human, players are rewarded with credits for each alien kill. These credits may be used to purchase new weapons and upgrades from the "Armoury". The alien team advances quite differently. Upon killing a human foe, the alien is able to evolve into a new class. The more kills gained the more powerful the classes available.
The overall objective behind Tremulous is to eliminate the opposing team. This is achieved by not only killing the opposing players but also removing their ability to respawn by destroying their spawn structures.
Main features:
- New flexible particle system for Q3 - can create smoke, water, fire easily in Q3 maps.

Cube is an open source multiplayer and singleplayer first person shooter game built on an entirely new and very unconventional engine.

Cube is a landscape-style engine that pretends to be an indoor FPS engine, which combines very high precision dynamic occlusion culling with a form of geometric mipmapping on the whole world for dynamic LOD for configurable fps & graphic detail on most machines. Uses OpenGL & SDL.

Allows in-engine editing of geometry in full 3D (you fly around the map, point / drag stuff to select it / modify it), which can even be done simultaneously with others in multiplayer (a first!). Has simplistic but effective fine grain vertex lighting that looks like lightmapping and can do dynamic lights & shadows.

Doesnt need any kind of map precompilation, even lighting is done on the fly. Has very simplistic quad-tree world structure that can do slopes (heightfields with caps) and slants, water, does decent collision detection & physics, has client/server networking that goes a long way in giving a lag-free game experience, and features a Doom/Quake-style singleplayer (2 game modes, savegames) and multiplayer (12 game modes, master server / server browser, demo recording) game with some uncompromising brutal oldskool gameplay.

Most of the engine design is targeted at reaching feature richness through simplicity of structure and brute force, rather than finely tuned complexity.

WESTBANG is a western FPS style game for Linux.

Comics

Files: DATA/COMIX/*.CMX

Comics are simple animations with given images made by a script file.
Comics are used for intro and outro animation and for interlevel shots.
There are these reserved comics:

intro.cmx played after the start of the program
gameover.cmx played, when a player loose his last life
goodbye.cmx played after the quit

You can modify these files as you wish, but you have to keep these names,
because they are called directly from the program. Other comics, their
names or number, is random.

Any of the *.cmx file can contain these commands:

delay < ticks >

Specifies the time the computer will wait before he does the next
command.

image < index > < name >

Image loads the specified bitmap and gives it an index number. In the
< name > can be just the name of the bitmap (the *.bmp file) or the path
and the name. The path starts in ../WESTBANG/DATA/COMIX, so all your
bitmaps and dirs have to be in the COMIX directory.

Note: The color 255,0,255 is transparent.

destroy < index >

Removes the image from the memory. Dont forget to destroy images,
or you can glut the memory.

virtual < v_index > < index > < pos_X > < pos_Y > < width > < height >

Virtual is the quad shaped object taken out of the image you can work
with by the commands of the comics. You can define more than one virtual
in one image.
< v_index > is the index given to the new virtual.
< index > is the index of the source bitmap.
< pox_X > < pos_Y > are the coords of the upper left corner of the virtual
in the image.
< width > < height > set the size of the virtual.

anime < v_inde x> < frames > < delay >

Makes the specified virtual the animated one. < Frames > is the number of
the frames and < delay > sets the pause between the two frames (speed of
animation).
Animated virtuals are made of bitmaps with all the frames placed in the
row. So the height of the bitmap is the same as the frames height and
width equals to times width of the frame.

anime_type < v_index > < type >

Sets the type of the animation of the specified virtual.
1: from first to last (1->2->3->...)
2: zig zag (1->2->3->2->1->...)
3: random

Example: These three commands make a short animated virtual.
virtual 3 1 0 0 10 10 //defines the first frame (size 10x10)
//taken from the image 1 (size 40x10)
anime 3 4 18 //makes 4-frames animation
anime_type 3 1 //sets the type of the animation to normal

setxy < v_index > < x > < y >

Puts the specified virtual on the given coords.

vis_on < v_index >

Shows the specified virtual. New created virtuals are hiden. You have to
use vis_on, if you want to see them on the screen.

vis_off < v_index >

Hides the specified virtual.

move < v_index > < tx > < ty > < sx > < sy > < tempo >

Sets the virtual as "the moving" one. Moving virtual goes automaticaly
from actual coords to target coords < tx >,< ty >. The speed of the motion
can be controled by the length of the single step (< sx >: step along the
x-axis, < sy >: step along the y-axis in pixels), or by the < tempo > - the
delay between the two steps.

resize < v_index> < sw> < sh> < speed_x> < speed_y>

Sets the virtual as "the resizing" one. < Sw> and < sh> are starting
height and witdth. Resizing can go by the very small steps, thats why
you have to set sw=100000 and sh=100000 if you want the starting size
of the virtual to be 100% x 100%.

sound < index> < name>

This is the same as the image command for the bitmaps.

play_sound < index> < volume> < panning>

Plays the sound once.

repeat_sound < index> < volume> < panning>

Repeats the sound, until you stop it by the command:

stop_sound < index>

destroy_sound < index>

Removes the sound from the memory.

pause

Waits for input. The script wont continue, until the user presses any key.

include < file_name>

Plays the < file_name> comics file. You can make the hierarchy in the files by this command. Its usefull for the good control of the long comics to create one "main" cmx file, that calls the single scenes as you can see in the "intro.cmx".

If you want to learn more, how to create the script look in our *.cmx files. Note: Max number of images is 50. Max number of virtuals is 50. Max number of samples is 20.

Hell World is a thrilling FPS adventure game which features excellent graphics, a dark atmosphere and an excellent scenario. Hell World game is designed to be a port of the Windows-only version of Hell World.
It is written using the openGL and SDL library and is developing for the last months by ironhell3.
The game starts from main.c There we call first two functions, sdl_init() and game_init() to initialise the sdl and game part of the game.After the succesfull initialisation of Hell World we loop in a while() function.Each frame we check the keyboard and mouse for events through keyhandler() and then render the game frames through loop().When we catch a done=true signal we quit the game.
Important:
1)We are in need of developers,musicians,artists etc to help develop this game
2)This game is released under the GPL license.Please READ the COPYING file for more info
Enhancements:
- Fixed movement
- Added fog
- Added crates
- Redesign of level 1 including texture changes

etvis is a demo viewer/commenter for Wolfenstein: Enemy Territory FPS game.
Demos recorded with ET can be sorted, renamed, deleted, and viewed. Comments can be stored for each demo individually.
Comments will remain no matter if a demo-file gets renamed by etvis or by another application.
For now you have to edit some things by hand before compiling, this will be changed in a later release:
Edit src/main.h EXECPARAMS for options to give to ET
src/main.c line 174 for the dir that is filled with your demos
src/main.c line 184 for your ET executable
Usage:
double-click on the filename to rename it
delete-key to delete the selected demo files
double-click views the selected demo in ET
Enhancements:
- A demo file can now be given as a command line parameter to omit the GUI, which is nice for associating etvis with .dm_84 files in your favorite file manager.
- In addition, basic gettext functionality was added.
