I have very fond memories of this game playing it in the early days on android after getting it for like 10 cents because Android store had that 1 billion app promo or something. It still slaps. Sure it is a lazy port but the nostalgia is worth the 1.17 euro I paid for it on sale. edit: This is a very nice game to open for 5-20 minutes at a time, same as on a phone. Very fun still.

This is an old game, but it is fun to play. Graphics are dated, but gameplay is exactly what you want with tower defense. Challenging, but not impossible. Infinite mode available. Unit type and placement matters. Tactics involved... If you like tower defense games, do not miss this one! This is top tier gameplay, even if the graphics are a bit... or a lot... dated.

I always find myself coming back to this game. It feels nostalgic {like, as in I played it in my childhood} but it only came out when I was 21 haha the way it looks and the way it plays feels very nostalgic and I love it. it might seem like a "simple" tower defence game but it's so damn hard sometimes- but its so much fun I don't even mind having to restart a level when I die. it's fun to come back and try to figure out how to win instead!

Finally found this game I love so much and use to play on the iPad... So happy it is on PC... Sentinel 3:Homeworld is very addicting. In my opinion is the best Tower Defense game that has ever existed!
