Good game - Good concept - Greedy Developers
The game in itself is fun and enjoyable. However the developers are too greedy and as a result ruined the experience.
When I say 'sparks', it means bought currency.
Two major gripe I have with this game:Inventory Slots
The one biggest problem I have is inventory slots. You start off with a tiny inventory which requires 'Sparks' to unlock FIVE slots. Then each additional unlock, the amount of spark needed to unlock an additional five slots becomes higher.
Currently I have 40 slots in my inventory and to unlock the next 5 slots, it will cost me $4+. Even parts you have equipped on robots count towards inventory so this gets filled up very quickly.Robot Slots
So you unlock a robot slot with sparks. But wait, they limit your inventory so you can't build anything with your new robot slot! Thus making you spend on inventory in addition to buying new robot slots. Crates
You would think the game had enough money sink? No. When you win matches you have a chance to get crates. To stand a chance to open these crates you will have to use sparks otherwise the picklocking tool has 0.1% ~ 5% chance depending on crate level. I have no problem with this in games but when you add in the other two money sinks then this makes the game have a bad f2p model.Conclusion
Stay away from this game unless the developer gets their head out of the gutter. Too many money sink. With the inventory limit it literally forces you to use sparks to progress. Yes you do get sparks in-game but no where near enough to make the game enjoyable on being free. I have no problem spending cash on a f2p game but there are too many money sink that are not really optional.
