You are the last chance for Earth, piloting a craft specially developed to engage these hordes.
You must fight your way through their defenses to the final goal, the alien base.
The final battle is about to commence! Halley Wars is a vertical scrolling shooter, and it's a sequel to the arcade game Halley's Comet .
The game has 6 stages set in locations in space such as, above planets or in asteroid fields.
There are end of levels bosses at the end of each stage each with their own weaknesses.
There are power-ups, which can be picked up along the way when you shoot particular asteroids or satellites.
These upgrade your weapon strength, speed, add explosive pods and shields.
Where the game stood out was, there are comets that need to be destroyed on your journey.
Each comet and ship that you don’t shoot makes it to earth and does some damage there.
Comets do more damage than the enemy ships do.
If Earths damage level reaches 100% the game is over.
For every 2000 points you score, 1% of Earths damage is repaired.
About Sega Game Gear
Sega's Game Gear (1990) was a technically capable handheld competitor to the Game Boy, notable for its full-color backlit screen — a real advantage at the time, offset by famously poor battery life. Its commercial underperformance against Nintendo's handheld means smaller print runs overall, and complete, well-preserved cartridges (the plastic shells are prone to yellowing and cracking) are a genuine niche within retro handheld collecting.
Gamevaro tracks Halley Wars for Sega Game Gear with separate market values for loose, complete-in-box (CIB) and factory-sealed copies, sourced from real eBay sales. Prices also vary by region — PAL, NTSC-U and NTSC-J releases of the same game often sell for different amounts due to print run sizes and regional collector demand.
Adding Halley Wars to a Gamevaro collection takes seconds — search by title or scan the box barcode, and the app fills in cover art, release details and current pricing automatically. This GG release dates back to 1992.
