  • Some very detailed and well done visuals.
  • The controls are simple and easy to use.


  • Game instructions are a bit brief and can confuse new players.
  • There are some definite difficulty wall issues.
  • Nothing especially new on offer; the game sticks to the basic tower defence formula.


The game isn’t bad; it’s just not one of the better tower defence games and may not be worth the current price.

Sentinel 2 is a tower defence game in which players must stop a large alien force from taking over the planet Earth. Like most tower defence games, players must build and upgrade various attack towers in order to kill off the advancing enemy forces.

Like most tower defence games, the controls are pretty straightforward. Players control their tower placement by selecting the type of tower they want to place and drag it onto the map. You can also unleash other powerful attacks, but only once you have enough energy to do so. The game’s controls work well, but the control instructions given to players seem rushed and brief, which will confuse new players.

The visuals look vibrant and are quite detailed. The sound is immersive and has a fun sci-fi feel, but players can choose to listen to their iPod during gameplay with no loss of sound effects. The game is single player, but scores can be submitted to a leaderboard and players can access OpenFeint to check your friend’s scores and other player stats.

Sentinel 2 – Earth Defence is a solid tower defence game, but there are some drawbacks. There is a huge difficulty wall shortly into the game that will hinder gameplay severely. And while tower defence games pride themselves on being hard; hard doesn’t mean impossible. Besides that, the battles themselves can become a bit boring after a while. So while this is a good play for fans of the tower defence genre, there isn’t enough new or enjoyable content here to keep you satisfied.
