End Missions Impossible

So I got the game a few years ago in iPad, then a few weeks ago in iPhone. I normally end up watching a tutorial because it’s too hard to just guess what towers you’ll need, but when I got to mission 12, the only tutorials are ones with the $1 packs and I don’t want to get them, so basically it’s impossible to get past 12😭 I really wanted to play the whole game tho (4/5 stars cause the game is still good tho)

My Favorite Tower Defense Game

I picked this game up back in high school, so I think it’s about time I write a review.

This is a wonderfully well done game with beautiful art, a fun story, great characters, unique enemies, and unique towers. It’s somewhat challenging but not impossible, and has enough levels to keep you entertained for hours, with an actual ending to top it off.

Some people have said it’s “pay to win,” and sure, it can be EXTREMELY difficult if you do not buy the tower packs, but it’s a free game so what do you expect? Most tower defense games that are free do not look nearly this amazing. The towers each have their own unique role and/or ability. They are designed really well. And all of the packs only cost $8 in total; the game itself is well worth $8.

I still come back to this game ever other year or so and play it through until the end. All in all, and amazing game, and I only wish they would make a second one.

Pay to win

The game is fantastic in the beginning! Good variety of enemies and weapons to fight said enemies. Being able to block the path so the enemies have to take a different path adds a whole new dynamic to Tower Defense games! Once you get a few levels in however, the game gets exponentially harder and encourages you to buy stuff with real money to progress. I don’t want to support this kind of mentality in gaming, so I’m deleting the game now instead of paying to get further where I assume they would force you to pay again. It’s a bummer because the beginning was so great.
