Not at all close in quality to halo wars 2 or even halo 5 (though that is pretty low except for multiplayer). ### 5/5 — Upgrade Tower Defence *2020-08-23, version 1.0.2* I love the game but the only thing is that I wold like to be able to get hero’s with the game money but other than that grate game ### 3/5 — HALO *2020-05-20* If you are someone like me and are into Halo 5 Guardians or Halo Wars 2 you will love this game cuz of the heroes and gameplay. They look like Halo five, and the gameplay is loke close quarters Halo wars 2. ### 5/5 — So cool *2020-04-08* They look like they unsc spartans ### 1/5 — Upgrade tower defence *2020-04-04, version 1.0.2* The adverts start as soon as the game loads. If I could have 0 Stars then I would have selected it. ### 1/5 — too strict *2018-12-15, version 1.0.2* doesnt allow you enough game progress unless you watch a million of the same ads ### 3/5 — Very similar to another app *2018-08-18, version 1.0.2* This is a very very close copy to another game called islands defence but the two games are made by different companies. I would love to know why the game has been re released as ultra modern? Big fan of the original game, it’s a shame it didn’t get any more content added to it and were also wondering if this version would? ## Frequently asked questions about Upgrade Tower Defense ### Does Upgrade Tower Defense have ads?
