One of my favorit games, easy to learn hard to master. The Ultimate Knight Windom XP is a console-like mech arena fighter. It's all about giant mechs fighting against each other in a destructible stage. With the PowerUp Kit and the latest patch there are 24 playable mech, and an NPC only warship. It sounds good, but first you need to unlock them by playing on the game. Some of the mechs shows similarities with other mechs in the same type, but all of them are unique in the terms of weapons, and movement options. There are transformable units, long range missile fighter álá Itano Circus, or massive heavy mechs.
The core gameplay is similar to the Virtual On and the Gundam vs. series. You can lock-on on one of the possible targets, and all of your shot (except the special purpose weapons) will target that opponent. Most of the weapons has more or less homing ability. All of the weapons can be set to different buttons, and has separate recharge time, but uses the same energy gauge. With the exception of the true long range fighters, every mech has melee weapon to deal with the close range targets. The melee attacks can be comboed, canceled, and even sometimes has special combo options. There are also a special option called OverClock. OverClock will enhance the regeneration speed of the weapons, the energy, and the boost, and decrease the cost of the special moves. You can anytime activate it if you have enough Ex.
There are also a special feature: you can make your own pilots. This mean, you can add voices (or basically any sounds) to the pilot. These sounds will be played during the corresponding events (for example when you attack, one of the attack sounds will be played). It is not hard to make a pilot, and it is really fun to hear your favorite character's voice. Of course you can add custom musics too.
The game quite superb in multi player mode. You can play it split-screen in the same computer up to 4 players (requires gamepad). Also you can play it through the internet up to 10 players, either by connecting to servers, or making one with the included server files. It is easy to use the server, just choose the game mode, and click on start.
This was a lot of writings. For some rest, here are two gameplay videos.
