Sentinel 4: Dark Star is now free for a limited time on the App Store (usual price $2.99/£1.99).
This special offer is in support of the Steam Greenlight campaign for Sentinel 4.
Origin8 are hoping that those who’ve played Sentinel 4: Dark Star on mobile will vote for the Greenlight to get a PC version of the game on Steam. Â It’s certainly one of the best Tower Defence series we’ve played and the latest game got our recommendation when we reviewed it last year.
You can grab the game free while the offer lasts on the App Store.
