It has been a hard month upgrading from Unity 5.0.4 to 5.4.4 and there have been some really unexpected road bumps. We still aren't fully 5.4.4 ready, but one thing has become clear, the Arena multiplayer isn't going to work. Between Unity 4 and 5.1 Unity's multiplayer backend fundamentally changed, but we always thought we could transpose our multiplayer code into the new system without too much difficulty. But we can tell you after 4 weeks hard at it, we have made no progress... at all. We have tried four new multiplayer solutions as well as made a good try to resuscitate the legacy networking from Unity 4 but at this point we feel that the mounting wasted time and dead ends are really hurting development progress. There has been considerable interest in a coop multiplayer mode. In the past we have posted why that would not be possible, as it would be like running a 300 player server on a local machine. So coop multiplayer wasn't part of the plan, but Arena was... The Arena multiplayer which we had hoped to deliver was at least something, but so far it has received very limited interest on the forums. So now we have hit this multiplayer upgrade road block and we need to make a hard decision. Do we keep pressing ahead on Arena multiplayer which likely will only have a small following and will take many more months than expected, or do we spend that time making the single player better. We think it is more important to make the game better. We have tried to make it very clear on the store page that in its current form SPAZ 2 is a single player game and we requested that people not purchase the game for multiplayer features not yet implemented, but we know many of you are still going to be quite disappointed. First of all, we are very sorry and embarrassed at this failure to deliver on our part. We let our enthusiasm get ahead of us. Secondly, we have contacted Steam and have asked them remove the two week since purchase time requirement for refunds. We are still waiting to hear back from Steam about this, but it should be possible. So if you picked up SPAZ 2 early and sat on it waiting for multiplayer, and didn't elapse the two hour playtime limit, you should be able to refund it soon. EDIT: Update from Steam: Their system is unable to remove the automated 2 week ownership time limit, but our Steam contact has kindly offered to handle the refund requests by hand. If you meet the refund requirements above and want a refund, please contact us at contact@spazgame.com with a link to your Steam profile, and we will forward your link to our contact for a manual refund. Above Refund Offer Available Until July 16 2017, need an end date else we will be pinging our Steam contact forever. Thirdly, we plan to use the time we recover to double down on content and replayability. We can get to these features sooner now and make them bigger. We are going to build new maps for the sandbox mode, release an greatly expanded set of sandbox gameplay mutators, add a much more difficult insane difficulty level, and we will focus on making the end game more challenging once you have that massive battleship. We hope that this will in some way make up for our failure with the multiplayer Arena mode. Currently we are still working on the upgrade to Unity 5.4.4 and it will feature DirectX 11 support as well as quite a bit of rendering optimization. Removal of the legacy networking hooks should also lead to CPU performance recovery. Once that is ready, we will dive back into work on the single player campaign at full speed to make SPAZ 2 the best it can be. Thank you for your support and understanding Andrew (Blorf) and Richard (Narlak)
