If you're unaware, Blaster Master is originally a very old series of games that started on the NES made by Sunsoft. After a long time in hybernation the IP was eventually given to Inticreates who launched this game as a soft reboot of the franchise with a pretty accurate recreation of the 1st game with a lot of Quality of Life changes and small rewrites here and there. You'll spend half of the game in a 2d sidescroller section using the Sophia tank to traverse the map similarly to a metroid game, and then the other half is spent playing a 3d top-down perspective shooter fighting many enemies in small maps and occasionally a boss as well.

The biggest change to this game is the story, which now has our protagonist Jason as a well researched scientist and his eventual support droid Eve who helps him trying to find his strange frog that escaped through a wormhole. The game isn't very difficult, in fact once you unlock a shield that works sort of like the Mantle from Binding of Isaac it becomes very easy to keep your gun level high to spam wave which is easily the most broken weapon shot type.

Slight spoiler warning, but you can only get the true ending of this game if you basically get 100% (iirc it's at least every sophia upgrade, but you might as well go the full mile at that point) which is a bit of a rude requirement, but it honestly doesn't take that much more effort to do so and I think it's worth adding since it unlocks some pretty fun new content and a really cool final boss. Overall it's definitely the weakest entry in the series, but if you enjoy the gameplay enough to stick with it then it's definitely worth your time!
