That’s what the author says about it:

Star Sentinel Tacticsis a turn-based tactical game that puts you in command of a squad of elite United Alliance marines – the Star Sentinels – as they battle to stop a race of bloodthirsty reptilians launching a devastating attack on our Galaxy! Along the way you’ll have to use sharp thinking and effective tactics as you encounter giant mechs, rotting zombies, mutants and a host of other foes – all intent on your destruction!

Star Sentinel Tactics takes the classic turn-based tactical combat strategy games, and brings them bang up to date with 3d graphics, realistic line-of-sight, an engaging story, and an array of new weapons and enemies. This is sci-fi tactical combat at its purest with all the focus on leading your soldiers through varied and engaging tactical situations to ultimately save life as we know it!
