Nemesis

Players control the Vic Viper through five levels, most based on levels in earlier entries, for a kind of 'greatest hits' of the series.

There is a cave level (as in level 1 of the original Gradius ), the mandatory Moai stage, a Gigeresque organic level, a graveyard (similar to bonus stages in the MSX and PC Engine version of the original Gradius) and a high-tech base.

Besides the classic core ship in the first level, all boss enemies are entirely new.

The cycling Gradius power-up system is reused here: collected power ups advance the power meter which can be activated at any time to gain the highlighted item.

The line-up includes the classic selection of speedups, missiles, dual shots, lasers, option satellites and forcefields.

The game allows players to start in any of the five levels and even to set the number of lives to a maximum of 99.

Nemesis for Game Boy is currently worth €47.59 loose, €61.00 complete in box, and €288.60 factory sealed. Prices are based on real sales and update regularly on Gamevaro.

Nemesis has a steady sales history on the tracked marketplaces, meaning it trades hands regularly and isn't considered particularly rare.

Loose means cartridge or disc only, CIB (complete in box) includes the original box and manual, and sealed means factory-sealed and never opened. For Nemesis, loose is €47.59 and CIB is €61.00 — CIB commands a premium because original boxes and manuals are fragile and often don't survive.

The PAL version of Nemesis is currently worth €47.59 loose, versus €45.28 for NTSC-U. Regional price differences usually come down to print run size and regional collector demand.
