X-It Again is an excellent remake of Psygnosis's puzzler for the Amiga, faithful in nearly every aspect. Profiles are used to save progress instead of passwords.

Much like Sokoban, most of the gameplay involves pushing blocks around to fill holes and getting your character to the exit tile. Instructions can be found inside the Documents folder, with some rather useful hints provided. All tiles are described in detail, for example glue tiles can be walked over but blocks get stuck when they are pushed onto them. Press the left control and Q key to quit at any time.

Xain D Sleena is an excellent platformer remake by X-Out, developer of the equally impressive Prototype. You assume the role of a soldier with a mission to save each of the five planets invaded by the enemy forces.

Each location consists of two equal parts. You have to fight your way to the enemy base station, detonate it and leave on your ship. The escape is basically a horizontal shooter stage with a boss in the last planet.

Plenty of options to tweak such as autofire, difficulty and image quality. Having to restart from a save point after losing all health may discourage a few players from playing much but fans of the original will cherish this remake.

Try setting Quality = 0 or Filter = 0 in the engine.cfg file if the game doesn't work at first.

XED is a decent vertical shooter by BomB that will please veteran shmup fans, but drive beginners mad even at it's default difficulty setting. The game sports great pixel graphics and consistent frame rate, though only two continues are allowed for each game.

Hold the left shift key for spread shot, and use the Z key for concentrated firepower. Your special weapon can be charged by destroying enemy ships, then activated by pressing the X key. A stage select feature allows players to attempt levels previously completed. The config file can be used to change key configuration settings.

XIQ is a game about trapping. Your avatar can fire in four directions, creating lines. If those lines form a box, the triangles in the box are destroyed and you score points.

Move with the arrow keys or joystick. Shoot in all four directions with W, A, S and D keys. Once a bullet is fired, it creates a trailing line. This line forms the edge of a box. Use four lines to create a box, trapping triangles inside.

Any triangle touching a line will freeze in place until that line disappears. Once the line disappears the triangle becomes quite anxious to collide with the player.

The amount of points you get for a box is dependant on the size of the box and the number of triangles inside it. Temporary powerups disappear after five seconds, but effects granted by the permanent ones stay until the end of the game.

Xoldiers is a new collaborative project by cactus and Terry Cavanagh, where players assume control over a squadron of soldiers on a mission to destroy as many enemy installations as they can. Use the Z key to shoot, hold the X key to take cover, press the C key to lob a grenade. Bonus points are awarded for efficiency and combo length.

An automatic online high score submission feature is included.

Xorpl is a short exploratory platformer with three endings. The game runs in a small window. Cursor keys can be used to control the main character.

XSketch is one of the many implementations of the popular word guessing game charades, where a group of people can join any table and attempt to guess what is drawn on the board for points. Some party games have stood the test of time, and as proven by XSketch the pen and paper game only requires simple technical updates to entice a new generation of audiences.

XWars is a decent attempt to fill the hole left vacant by the forced withdrawal of Grid Wars. There are no configurable options yet, though gameplay is practically the same bar some minor sprite changes. Dual analog controllers are also supported in the latest version.

Your ship can be moved around using the W, A, S and D keys. The mouse can be used to aim at other vector shapes. Indicators shown at the top of the screen provides information on the next upgrade or multiplier increase at a glance. A worthy substitute, especially with a little more work. Made using the HGE engine.

In xWUNG, you play by moving the mouse to swing a ball. The ball's attached to a wire, and both of them kill enemies on contact. Be careful of the debris as it's deadly. There are bosses that appear with regular intervals. Make large combos to get good scores.

This version of xWUNG is a port of cactus' earlier release, originally created using the Game Maker engine. You play by moving the mouse to swing a ball. The ball is attached to a wire, and both of them eliminate enemies on contact. Debris will destroy your ship, so avoid them whenever possible.

There are bosses that appear with regular intervals, and new enemies are introduced as the game progresses. The single power-up found in the game allows you to nullify certain enemy projectiles. Good scores can be achieved by making successive combos.
