Just in time to celebrate UK’s Bonfire Night (aka Guy Fawkes Night), Origin 8 have decided to share the love and make their popular TD game Senitinel: Mars Defense as a free download for an entire week. As one of the more challenging tower defense games at the App Store (at least in my opinion), Sentinel was the first iDevice TD to integrate a Sci-Fi theme that included some unique and much welcomed features . If you’ve yet to play this Origin 8 offering, now would be a great time check out the full version FREE! As well, if you like what you see, be sure to check out its sequel, Sentinel 2: Earth Defense.
