Some relevant shmup releases this week, covered as part of Retronauts round-up are:

G-Mode Archives+ version of Argus:

What’s this? A mobile phone conversion of NMK and Jaleco’s 1986 arcade shooting game Argus, originally released for Japanese feature phones in 2003; this port valiantly attempts to recapture all the features of the original, which include a Xevious-esque air-shot/ground-bomb system, the invincibility power and the end-of-stage landing runway sequences.

And Over the Horizon x Steel Empire:

What’s this? An emulated three-pack containing the original Sega Genesis/Mega Drive version of Hot-B’s steampunk-themed horizontal shooting game Steel Empire, the Game Boy Advance remix of said game and the 60Hz NES version of Over Horizon, another Hot-B horizontal shooting game that was only released in Japan and Germany.

Thanks to Retronauts for covering these releases!
