I'd by lying if I said I missed the days when blasting invading space craft with 8-bit energy beams cost a pocket full of quarters. The gameplay itself, however, remains a treasure of nostalgia. One that Syder Arcade HD is blatantly exploiting to get $1 from me and I will happily pay it. Why? Because blowing crap up is awesome.
The game is a top-down free-scroller, which means you actually have a level of control over your movement.
