Ashura Blaster is a vertically scrolling shoot 'em up arcade game released by Taito in 1990. The player controls a helicopter (selecting 1 of 4 bomb configurations) and shoots enemies in the air and ground, collects power-ups, and defeats bosses to advance levels.
The kanji characters on the titlescreen read 'Ashura'. Ashura is a demon related to fighting. (Wikipedia)
Here's another of those self same, vertically scrolling, two player shoot absolutely everything that moves, or indeed doesn't, games. It's called Ashura Blaster and it comes from the Taito stable. The main characters here are two helicopter gun-ships battling their way through a rather hostile environment. As well as your forward firing gun doopha you can buy different extra weapons and you also have a supply of bombs. Some of the enemies hurl about a ton and a half of hot lead at you, making survival a tad on the questionable side. Oh, and when you get hit, your helicopter does a crap shrinking actsupposed to simulate your falling to earth I suppose. Two helicopters make progress a bit easier, but all in all I found it rather uninspiring. Save your dosh. (scan)
