UFO: Alien Invasion is a 3D UFO-inspired tactical game.
UFO: ALIEN INVASION is a strategy game featuring tactical combat against hostile alien forces which are about to infiltrate earth at this very moment. You are in command of a small special unit which has been founded to face the alien strike force.
To be successful on the long run, you will also have to have a research team study the aliens and their technologies in order to learn as much as possible about their technology, their goals and the aliens themselves.
UFO: Alien Invasion is heavily inspired by the X-COM series by Mythos and Microprose. The first game of the series, UFO DEFENSE, became a classic and, in our honest opinion, is one of the best games ever made.
UFO: Alien Invasion is neither a sequel nor a remake of UFO DEFENSE - we simply had the urge to create a similar strategy game, which will hopefully be as entertaining as the original was for the players (and for the developers, of course). Join the IRC-Channel at irc.freenode.org named #ufo:ai and contribute to the developing process.
Gameplay:
The game is turn-based. Well, this might sound somewhat old school now, but trust us: turn-based games are fun!
Each member of your squad has a limited number so called "time units" each round, which are consumed when you order the unit to walk, to fire a weapon or to perform any of the other miscellaneous actions. When all your forces are out of time units, the aliens turn starts. In addition to eliminating as many enemies as possible, your mission is to minimize civilian casualties as well as to acquire parts of the advanced alien technology.
Once youve acquired sufficient samples of the unknown technology, your research labs will be able to reproduce the alien weapons and devices in order to use them against their original creators.
Game Engine:
The game engine is based on a heavily modified version of IDs Quake2 Engine. This doesnt imply that UFO: Alien Invasion is a mod or a total conversion at all! No, UFO: AI is a stand-alone game which doesnt require Quake2 or any similar program to run. Our self-developed game engine is featuring up-to-date OpenGL graphics and special effects, increased texture resolution, hardware accelerated clipping of map layers to toggle between floors, a new animation system for player models, a stunning AI and a few other gimmicks.
Multiplayer support:
You can play UFO: ALIEN INVASION with your friends via LAN or Internet. One player takes the role of the human special squad while the other is in control of the alien invaders. Co-op team play with multiple players on both sides is also supported for up to three teams on each side (6 players total).
Enhancements:
- Implemented sv_roundtimelimit cvar to set the maximum time a team has to finish their round in multiplayer.
- Completely rewritten saving and loading system.
- Finished implementation of Flashbang - now Flashbang will disable enemys reactionfire as well.
- Reintroduced employees renaming again.
- Hire menu and Team Select menu now shows Health bar as well.
- Heavily improved chat subsystem for multiplayer as well as Multiplayer Team Selection menu.
- Improved describing weapons and ammo in UFOpedia and other menus, including displaying firemodes.
- Added multiplayer server password protection.

Alien Perl module package contains external libraries wrapped up for your viewing pleasure!

SYNOPSIS

perldoc Alien;

Alien is a package that exists just to hold together an idea, the idea of Alien:: packages, so there is no code here, just motivation for Alien.

Why

James and I ended up doing a build system for Fotango, lots of people have done a build system, it is a pretty boring task. The boring task is really all the mindlessly stupid things you need to do to build C libraries that Perl modules require, these C modules usually have unusual installation systems or require vastly different options. So CPAN modules install easy, 3rd party stuff is nasty.
So, suddenly an idea struck me, Alien packages! Imagine a CPAN module that has as its only task to make sure a certain library is installed! That means that you can write all the voodoo in your Build.PL file and then just make sure the module requires the correct Alien module! Then anything that install Perl modules will deal with it automatically!

How

So, what should an Alien module do? It should make sure that the target is installed and it should provide the caller with enough information to use it.
The idea is that you use it to make sure it is there, and you call class methods to find out what to use. These class methods will be individually specified by the stand alone Alien modules.

No Framework!

The reason this is so loosely worded is because we have no idea what common functionality will be needed, so we will let evolution work for us and see what individual Alien packages need and then eventually factor it out into this packages. I would like to avoid a topdown design approach.

Responsibilities of a Alien module.

On installation, make sure the required package is there, otherwise install it.
On usage, make sure the required package is there, else croak.

Bundle the source with the module, or download it.

Allow module authors to access information it gathers.

Document itself well.

Preferably use Module::Build.

Be sane.
