The eXceed Collection... What is it? It's a set of three shoot 'em up games brought together in one budget package. What's special about that? Well, the eXceed series is relatively popular bullet hell in the "doujin" game world. In case you didn't know, doujin is sort of akin to our term "indie". A doujin series you might be aware of is the extremely popular Touhou Project games.
The collection includes the following games: eXceed - Gun Bullet Children, eXceed 2nd - Vampire REX, and eXceed 3rd - Jade Penetrate Black Package. If you can manage to ignore the awkward and humorous names then it's a nice set of titles for $10. In case you don't want them all, then it's also possible to buy each game separately as well. In case you're not ready to make the purchase, the trio of games can be demoed on their official site.
