So here’s the breakdown. MechWarrior Online is the multiplayer shooter developed by Piranha Games based off the longstanding single-player series of shooters. Piranha Games later started work on MechWarrior 5: Mercenaries, the single-player shooter that’s an actual sequel to the prior series. And it has been delayed a lot, getting delayed again to December 10th of this year when it was originally planned for 2018. It’s also now being sold as an Epic Store exclusive, with no way of playing the game without going through that particular storefront.
This has some players up in arms in no small part because they had already paid for the game months ago without any announcement of platform exclusivity. Piranha Games has offered to refund anyone who no longer wishes to purchase the game, with refunds open until September 1st and the special items that had already been offered for MWO not being revoked for refunds. It’s kind of a tangled mess, and your mileage will vary for whether you think it’s a tale of greed, a minor change in storefront, or just a reminder not to pre-order things this far in advance.
