Ratings and Reviews
Better than before
Sentinel 3 homeworld was probably my favorite tower defense ever. And I really was skeptical after reading other reviews before I downloaded sentinel 4. Now after playing through all difficulties including psycho I am definitely a huge fan. They outdid themselves this time. I thought the enemy being able to damage your towers would take the fun out of it. However it made it a wonderful challenge and they balanced the game with auto repair and the drones repair relatively quickly. Also the larger size of the super towers was disappointing but it you plan carefully you can beat any difficulty. You don't even need to spend money on star fragments. Also I got the juggernaut after I beat the game and he is a wonderful commander addition. The price is very reasonable. Support the game! It's only $0.99 don't be cheap. They don't have obnoxious adds and it's a great game.
Possibly the best Tower Defence Game Yet
I play a lot of TD games, and this one has it all. It’s challenging without being murderous; weapons and upgrade progress is reasonable (you don’t have to spend additional cash, although in the end I did just to reward the developers for a great game). There is so much to upgrade that it doesn’t get boring as you move up through the levels.
Crashes on mothership
Please fix the crash that occur when the big behemoth arrives. There is simply no way around the crash as multiple restart of the game does not solve the issue. The game always crashes after a certain amount of health has been lost by the big behemoth (game crashes usually around when the behemoth has around 45-55% health remaining).
The current issue makes it so that its pointless to play the endurance/endless modes since once the big ship arrives, game crashes. Some of the later missions on campaign two are also not possible to complete as the final wave always contains a big behemoth boss.
