The paid version of Templar Assault RPG is on sale for 99 cents this weekend. It's a squad based SRPG. Check it out. The same guy also makes a fantasy based SRPG.

Templar Assault is an older game, but still really fun if you like Space Hulk or Aliens. They're also making a sequel based on the same engine they used for Heroes of Steel, a Fantasy dungeon crawler. Both are turn based. https://play.google.com/store/apps/details?id=com.tresebrothers.games.templarselite&hl=en
