Warblade is a shareware computer game for Microsoft Windows and OS X, written by Norwegian developer Edgar M. Vigdal. The Windows version runs well on Linux under Wine. It is also available for retail in the App Store for iOS devices (in iPhone/iPod Touch and iPad versions). The game is a 2D space shooter in the vein of the perennial classic Galaga. It is a rewrite and modernization of a popular Amiga shareware game, Deluxe Galaga, which was written by the same author back in the mid-1990s. Where technically possible, the graphics and sounds are respectful to their Amiga origins. Gameplay The player controls a small ship, which moves along the bottom of the screen. An assembly of bug-like alien creatures fly onto the screen and shoot at the player's ship.

On defeating some aliens, random bonuses will be dropped for the player to collect, such as money, improved weaponry, or mini games. Levels Levels are made in packs of four, with each pack introducing a new alien design. The first two levels of a pack are levels containing only small aliens. The third level introduces larger versions of the aliens. When defeating a larger alien, there is the opportunity to collect a rank marker. When six different rank markers have been collected, the player advances a rank. The fourth and final level of the pack, alternates between a kamikaze level, in which aliens dive from above the screen, and a bonus level, in which the player earns a bonus if all aliens are defeated before they leave the screen area. Every 25 levels there is a boss level. Shop At the end of each pack, the player is taken to the shop where there is the option to purchase upgrades, such as extra lives and improved weapons.

If all pairs in a memorystation are found, the player receives bonus points and the next time a memorystation is entered there are more squares. Meteor Storm A meteor storm is the second mini game that can be entered by collecting a falling bonus from
