The Local Battle is the only one mode which not let the players to use items or colours. This game mode is similar to the Online Battle mode, but it supports only four character at the same time (players and AI bots together). This requires at least one controller connected to the PC, and can be played with maximum four players. The Local Battle mode allows the players to play on the same computer in split-screen. There are a total of eight game-play modes: Arcade, Survival, Practice, Team Battle, Blitz Tactics, Hangar, Local Battle, and Online Battle. The game follows an unlocking system, where finishing 'Arcade Mode' in any level of difficulty with a specific mecha enables the player to unlock a new one for customisation and use in all other modes. The mechas are named after operating systems for computers (such as Windom or Linux), sometimes with slight variations, or using the codename of the operating system's development version (such as Vienna, Blackcomb). With v2.005, another two were added, bringing the total count to twenty-four.

On its initial release, the game had seventeen different mecha for use. Ultimate Knight Windom XP and its expansion pack (PowerUp Kit) still available for digital download on some Japanese websites. In November 10., 2016 the website of Project Windom was closed, officially announcing the end of the Windom game series. Unlike the PowerUp Kit, SV Lite was never translated and is only available within Japan.

Kamada later went on ' Ultimate Knight Windom SV Lite', which succeeds the PowerUp Kit version with a redesigned game engine. The author had released both English and Japanese versions only for versions 1.007 - 1.009 patches. Additional patches was released later on, leaving the game's final version at ver.2.008. This patch was the first which resolved the PowerUp Kit's delay in handling functions, make the online mode more welcoming by resolving the slow network latency problem that was present in older versions, and resolved the issue of random slowdown for singleplayer game-modes. The Project Windom planned to release another retail expansion, but they decided to release as a free patch, numbered as ver.2.005. The expansion received four patches up to ver.2.004. In that version, the original game engine was modified to include more scripting commands and in-game features, and added compatibility with the newer operation systems. An expansion of the game called ' Ultimate Knight Windom XP - PowerUp Kit', was released in Japan on December 17. On January 6, 2009, Curious Factory released a trial version in English and on February 7, the game was on the market. Various patches were released, encompassing version numbers ver.1.000 through ver.1.009. This version was released in both English and Japanese. Kamada released the first version, entitled 'Ultimate Knight Windom XP'.
