So many issues…

I don’t get rewards for milestones… I feel like this game is so corrupt in doing everything possible to try and get players to spend hundreds of dollars in order to progress…. It’s really depressing tbh…

Fun and relaxing (sort of)

This game is simple but great! It’s fun to watch your weapon selections play out, work together and do their thing.

However, some of the guns could use an intelligence upgrade. The Disruption Drone, Laser and Tesla Coil has a bad habit of literally firing at nothing, or missing out on shots that can do the most damage. (Aiming at one target instead of the group of 20, for example.) Upgrading that would take away the only real point of frustration in the game.

(UPDATE): Still waiting for the weapons intelligence upgrade. Some weapons literally shoot at nothing, making the gameplay EXTREMELY frustrating. You spend upgrade decisions to create powerful guns, only to seemingly have them manned by incompetent toddlers. THIS HAS TO BE FIXED! I downgraded my game rating to 3 stars because of weapons incompetence.

Also, while all of the item collections may seem bountiful and cool, the stuff to collect are spread out over a dozen pages or more. Anytime I want to play, I end up spending the first 15 minutes going around multiple pages to search for and collect things. If the collecting could be consolidated so I can just grab stuff and then start playing sooner, that would be more fun and efficient.

Avoid

Middle of gameplay every 10 seconds gameplay stops to select a power up card rather than automatic upgrade during gameplay. Unfortunately this is the way of games now.

Really?

Was playing the game having a good time untill I was forced to watch an add and it wouldn’t let me go back to the game ..
Had to close the game and re open it just to have to restart all over again ….

This is a good way to make people delete the game …..
