So been playing for around 4 weeks, and I have so far mostly enjoyed my experiance with the game.
Interesting story, great character and mech designs, good voice/music.
We don't get full control over our mechs in the battles, but we can at least see them move around and carry out there attacks.
F2p for the most part, and while some rewards are decent, what we get from mission to mission is next to nothing in regards to the premium currency or upgrade materials. And the Skins!!!! While very well done, many cost in excess of 1000 of the premium currency... for comparison a 10 pull of rare mechs or characters (in reality i’ve only gotten 2 characters on a 10 pull, the rest were affection gifts for increasing stats) will cost you 2000 of the premium currency. For something that is cosmetic only I feel its a bit high, but just my opinion. Its an optional feature, but one that can get very costly.
Events are all doable f2p, but you will have to grind them. From the 2 events i have seen, each usually lasts a month, so plenty of time to get all the associated rewards.
The game like all f2p is a GRIND when it comes to trying to get the more rare mechs and items, but is fun overall.
