Between the large numbers of FPS games, and the RPGs, Bullet Hell shooters are sadly under-represented on Steam, and in fact, in Western gaming in general.

Jamestown is one such example of a Bullet Hell shooter. It gives you a variety of ships that you can use to pummel through a variety of enemies, while at the same time trying to avoid getting pummeled yourself. It's very lenient on lives, and the levels are short, so if you can get used to levels one at a time it's not a particularly difficult bullet hell, but it serves its purpose well and is highly recommended if you're a fan of scrolling shooter type games, or perhaps are looking for something in a genre you have not had any chance to play yet.

It's very inexpensive, so worth a buy.

SpaceChem has the potential to become synonymous with hard. Not hard like insane action game hard, oh no, this is perhaps even more intense. Bond molecules, break molecules, form new molecules and output them from the reactor. Then when you think that's all there is to it, you zoom out and realise there's sometimes more than one reactor! The learning curve is pretty steep, but the tutorials give you a good staring point. If you don't like using your brain, I cannot recommend this game. If you do though, then get your thinking caps on because we're going to do some chemistry!

Disclaimer: Chemistry not actually real. Don't try breaking strong bonds at home. Free atoms can (and probably will) cause nausea, hearing loss, pain, death, and even explosions. Not for the faint at heart.

I could describe this game as Portal with the portals replaced with a giant metal ball and Source engine replace with Unreal engine. In portal you defend yourself with a cube and a portal gun. In The Ball you defend yourself with a ball and a... hammer gun that doubles as electromagnet. This doesn't mean The Ball is not unique though - far from it. It's one of the most original games I've seen in a very long time, and you're sure to love it right through.

In short: If you loved Portal, you'll probably love this game - pure genius.
