Alien Shooter < Shadowgrounds

I know that I'll get blasted for saying this, but flaws aside, the gameplay in Shadowgrounds in better then that of Alien Shooter. The ability to dodge coupled with the more difficult damage model adds the tension of a shmup. The only thing that I think Shadowgrounds could really use is a survival mode. Thankfully, there is a growing mod community around it, so that could happen soon.

If you think about it, these top-down shooters are really shmups with deeper gameplay and different theming.
