Preview: Sentinel 3: Homeworld

Sentinel 3: Homeworld is a sci-fi tower defense game by Origin8 that places players on an alien homeworld in a battle for survival.

As traditional in the tower defense genre, players must combat waves of enemies as the defend their base from destruction. In Sentinel however, you often must defend multiple fronts as enemies enter at different points in the map, and utilize your unique commander unit to help turn the tide of battle in your favour. Enemy units must take down barriers before they gain access to your base, which once taken down, ends your mission in failure. The barriers themselves are armed with turrets, and in the early stages of a mission can be used to supplement your commander and towers to fend off attacking foes.

While many often enjoy the strategic side of tower defense, Sentinel adds a great deal of depth by rewarding players with coins and experience at the end of each mission. The coins are used to unlock turret slots so that you can carry different types of turrets into battle, whereas the experience points allow you to upgrade your commander unit in a traditional rpg-like fashion, increasing stats like attack damage and health. This player-defined progression is unique and enjoyable as it forces players to make difficult choices regarding what tools they bring into battle and how they wish to utilize their commander unit. In the end, Sentinel 3: Homeworld is an engaging experience that fans of the tower defense  genre will love for its unique gameplay and player progression.
