Invasion is a team based gametype which comes standard with UT2004 and with UT2003 via bonus packs. This gametype uses Deathmatch maps as its map list.

Description[edit]

Alongside the other players, you must hold out as long as possible against the waves of attacking monsters.

Invasion Gameplay[edit]

Invasion is a Team Game, but not in the conventional style. Every player is on the same team (red) whose goal is to survive waves of attacking Monsters. You are given a radar map to help you see the locations of your teammates and the Monsters. The game starts with a small delay before Wave 1, so that your are able to obtain weapons. After this period a 10 second countdown beigns, after which hostile Monsters will spawn at Player Starts. You must destroy these Monsters for a given length of time to complete the wave. Then the 10 second countdown will begin for Wave 2. Rinse and Repeat ;).

If you die during a wave, you are OUT for the remainder of that wave and you will have to scramble for weapons at the beginning of the next wave. If at any stage All players are OUT, the game is over and you have lost the match. If at least one player survives each wave, after a configurable amount of waves (maximum and default 16), you will win the match.

Sounds easy? Not quite, as each wave is harder, introducing greater numbers of more difficult Monsters.

Mods for Invasion[edit]

Invasion in its raw form is much less popular than highly modified versions of the Gametype.

Many UT2004 servers operate with one or more of the following modifications:

Also worthy of mention is Fraghouse Invasion, a complete rework of the invasion gametype by the Fraghouse mod Team. This Mod offers support for vehicles and a complete new set of weapons for your enjoyment.

Discussion[edit]

Nick89: 10 pages requesting! Not anymore ;) I thought i might help out :) Still very much a work in progress, feel free to rewrite everything ;)

SuperApe: Thanks. You da man. Yeah, I've probably been the one "requesting" this page in regards to Monsters, etc. We really should have more Gametype pages for DM map games, but LastManStanding is actually a class name for the old UT GameInfo version. Not sure what to do about that one.

Nick89: Nice edits :) Just a question, do you use some sort of program to parse these files and to create the API's that you put here? Or do you do it manually?

SuperApe: Manually. I even do HTML manually. :D But, I know I've seen mention of some kind of Wikifier somewhere around here. (Class Wikifier) After a while, you just get to know the pages that need linking to, what words need [['s and such.
