In Dark Star, you are back as the commander of a beleaguered base set in a hostile alien environment. You have to put up a spirited defense by building powerful towers around your command post. Hordes of alien attackers will try to destroy your defenses in order to conquer your main command post and end your existence on Dark Star.

The storyline is pretty straightforward and old hat but for serious fans of tower defense games, Sentinel 4 is another welcome addition to their collections.

The game takes you directly to a campaign. You can immediately build towers by dragging and dropping them on strategic locations around your base. You can fortify every tower and equip it with deadlier weapons system using the credits you earned for each kill. Additionally, you can now employ a Sentinel Hero Commander in any nearby tower to strengthen its defense. You can also deploy your own hordes of troops to delay and weaken advancing enemy armies.
