Also while pulled by the maker due to a kind request (not sarcastic) by the dev'rs of Geometry Wars, you can easily still find it online by checking out the 'World Of Stewart' and doing a +Grid Wars v5.4 (or something of the like) in google.
That sucker uses dual analog or whatever you wish and hits the gameplay damn nicely true to form, a bit too true hence the 'pull it please' request.
