Gamma Zero

This is a very crisp old school shoot-em-up bullet hell. I wouldn't say there's anything groundbreaking about the game, but it's a fun playthrough if you like the genre.

Gamma, the powerhouse of the trio, trades agility for destructive coverage, appealing to players who enjoy wide attacks and raw strength. This trio of opt…

Got it for a dollar on Fanatical and I'd say it's worth it. A nice shmup to put a few hours in and replay occasionally if you want. That being said, I think I've had my fill and will also concede on the rest of the achievements (the completionist in me weeps, but I know my limits).

Somehow after many games like this, i only found out through this game that the genre is called 'shmup'
