Ever wondered "Which computer operating system would win in a battle if they were Gundam-likemechas?". Look no further with than the Windom XP series by doujin circle Project Windom for PC!Initially named Bootfighter Windom XP SP-2, this series of games started as a Freeware Game based on the popularity of the Gundam VS Series. Initially featuring fourteen mechas based after Microsoft Windows and Linux operating systems with four game modes. The original game was fan translated by mirror moon and you can find it here (it is, however, outdated as the current release is v1.200).It was subsequently followed by a retail Mission Pack Sequel titled Ultimate Knight Windom XP, which adds new mechs, a fairly difficult Arcade Mode, equippable items, general gameplay tweaks, and balancing to the roster. An Expansion Pack called Power-up Kit was later released during Comiket 77 that adds new stages (two stages from the original Bootfighter Windom XP SP-2 and one new area) and five new units. Ultimate Knight Windom XP was picked up for an official English release by Curious Factory on July 2nd, 2009 and it was released via Digital Distribution through their website and GameflyDRM-free, however it is outdated since it lacks the additions from the expansion pack and later updates. Thankfully there are fan-made translations for the expansion pack release of the game from a few forums dedicated to the game.Further development for the Ultimate Knight Windom XP ended with v2.008 as Project Windom is currently working on another follow-up for the game titled Ultimate Knight Windom SV, one aiming to become more akin to Mobile Suit Gundam: Extreme Vs. in terms of gameplay. A trial version of Ultimate Knight Windom SV, aptly-named -Lite Version-, has been released at Comiket 83.The Windom XP series owes its spotlight and life though to the spread of its translated freeware version, followed later by the spread of Ultimate Knight Windom XP and the popularization of its fan mods and videos.
Air Jousting: Linux Anisum when performing aerial melee attacks.
Alpha Strike: Windom Talisker WP and Windom BlackComb's last sub-weapon.
All There in the Manual: The little information about the game's mechs, the pilot creator and even the default cat-pilots are in a rare file that came with the original games bought from the website, and later lost through massive file-sharing.
Battle Ballgown: Linux Cymbidium, Ranunculus, Anthurium, Fennel, and Anisum are designed with them.
Battleship Raid: The Blitz Tactics Mode, where you and a team of mechs try to destroy the opposing team's battleship.
Beam-O-War: A VERY RARE instance, and only possible through the battle between two KD-07 BlackCombs since by default, the beam projectiles go through each other. Should both face each other and strike at the same time with the sub-weapon or block an incoming beam, it results in a beam pong that will only end until either sub-weapon or the blocking fail.
Beam Spam: The KD-07 BlackComb and KD-06 Windom Vista being the most popular Windom to do it, though the MS-98 and Millenium suits have a special grenade that rains beams upon the area.
Some of the Linuxes like Iris and Primula are able to invoke one of those magical spell circles that spam several medium-ranged beams, and a few long-ranged ones.
BFG: KD-08-3 Anthurium Linux and KD-06 Asteroid Windom 2000 SP1's guns. Linux Anisum has lance that doubles as a cannon.
BFS: KD-05-3's Anti-Ship Sword, with the KD-07 BlackComb having a pair of then. And then there's KD-08-2 Linux Cymbidium's power-up sub-weapon move, which basically gives her sword a huge laser blade. Linux Ranunculus can also one for melee attacks.
Cool Sword: Linux Ranunculus and Fennel fight with them.
Cut and Paste Environments: The "In" maps are basically this. The In1 being what could be a never-ending hangar, while the In2 is basically a bland section of box-rooms.
Deflector Shields: Added in the v2.005 update for the new Linux unit it provides. The Windom BlackComb however had from the beginning a deflective armor instead of a shield similar to Destiny's Akatsuki Gundam, that recharged the energy meters while reflecting beam shots and absorbing bullets. It was however vulnerable to melee, missiles and other attacks.
Die, Chair! Die!: Wanna destroy the city's buildings around you with your infinite supply of missiles and beams? Fire.
Difficult but Awesome: The MS-98 Windom, the Zaku's equivalent of this game, has the poorest of all health and boost meters, speed and melee damage attacks. On the other hand, it comes with the lowest cost in the battle meter, quick boost recharge, five lives, and its machine gun and grenade attacks can overpower any unit when used right (especially the latter).
Same for the Linux Anthurium: No melee, no blocking, rapidly empties the power meter and thus is vulnerable to any kind of melee attack... But compensates the lack of these with a variety of specifically made emergence attacks for these situations.
Double Unlock: In Ultimate Knight Windom XP, Windom Talisker WP and Linux Anisum requires you to beat the Arcade Mode with all the other Windoms and Linuxes first to unlock Windom Vienna and Linux Primula respectively, and then beating Arcade Mode with the mechs that Vienna and Primula unlocks (as of v2.008).
Fake Difficulty: It's been noted that some of the last few stages in Ultimate Knight Windom XP's Arcade Mode since the expansion pack update (v2.000 and above) puts you in a hopeless fight against mechs that are over-powered compared to you and your sorry excuse of an ally. Even on Easy the A.I. will pretty much win 99.9% of the time. Good luck testing your patience against the final levels without raging or resorting to cheat programs to tip the odds in your favor.
Fem Bot: All Linuxes, save for the KD-07-2 BlackSelena.
Flaming Sword: KD-08-6 Linux Licorice was initially presented with a flaming katana. After the v2.005 update, the katana is no longer permanently on fire. It needs to be manually ignited, and the function to do such replaces her Double Jump ability.
Game Mod: Hoooooboy, and it's the very thing that keeps this game alive and out of obscurity, going from Fan Translation of the menus to an entire change on the mechs and maps of the game.
No less than three forums mostly dedicated to this, one of them being the popular 3DGundam community, well known for creating detailed 3D models and artworks of Mechs, many of which end up applied to the game! Unfortunately, the forums has been shut down.
Leeroy Jenkins: The NPC's default strategy, even when clearly outnumbered. This becomes especially clear in the Arcade Mode where your teammate will throw themselves against the enemies and die seconds later, either rapidly depleting the battle cost meter and making you lose or leaving you to face the onslaught on your own.
In the worst cases, such as when you're both targeting the same enemy, much friendly fire ensues and gives the enemy just the right window needed to turn the tides on you.
Loads and Loads of Characters: The game itself has over 20 characters, but the mods available allow you to replace these characters AND add several more, within a limit of 50.
Mecha Pincushion: Linux Ranunculus has a special attack where she stabs a mech with her BFS, summons a bunch of smaller swords and skewers her victim with the swords just before pushing them off her blade. Her ranged attack can also leave her opponent as such after summoning lots of swords.
Mercy Invincibility: After receiving a certain amount of hits, your mech goes down and the rule is applied until it gets up and either begins firing again or the invincibility time runs out.
Mirror Match: Rarely in the Arcade Mode, though common in the other modes.
Missing Backblast: Subverted with the bazooka gun for the Millenium and XP series as they have the special effect of the back-blast, yet no recoil on the mech itself.
Averted when using the sub-weapon, like the missile launchers or the bazookas themselves.
One-Hit Polykill: With any kind of beam rifles, since the beams will only cease to exist if they hit one or more buildings, the floor, reach a certain distance or time length.
Rank Inflation: The items you get in Ultimate Knight Windom XP's Arcade Mode. They go by D, C, B, A, and finally S.
One of the last stages of the Arcade path puts you against the KD-07 and KD-07-2, the Windom versions of the Strike Freedom and Infinite Justice (not counting the Akatsuki parts in each Mobile Suit). Good luck fighting Kira and Athrun at the same time.
Skybox: A circular and static skybox, noticeable if you fall off the map (especially in the Skyland map) or fly too high without the map boundaries (by deleting the "Hit" files from their folders).
Sky Surfing: The shield for XP (KD-05) and XP Type-B (KD-05-2) can transform into a sub-flight unit that the mech rides on top of.
Swiss-Army Weapon: The KD-06 Asteroid Windom 2000 SP1 and KD-06 Asteroid Windom 2K's guns, with a normal or a spiral beam shot as the main mode, a bazooka gun mode for the last aub-attack and a Wave Motion Gun for the fighter ship mode.
Whip Sword: Linux Cymbidium's power-up sub-weapon gives her a huge bending beam blade to her sword that works mostly like a whip, capable of hitting multiple enemies around with the right combo at the right time.
