How to get more concurrent players into Immune?

That question kept us awake for the last few updates, because Immune is most fun if played together with other people. After many attempts to solve this riddle, we now chose to turn Immune into a free to play game over the next few weeks. This probably is the only way for us to ensure Immune is the multiplayer experience we want it to be.

That being said, we won't turn Immune into pay to win. With this update we turned hats into Steam Inventory items instead of ingame items. You now get hats from cases, which have to be unlocked with keys. You have a chance of getting a case dropped when solving missions.

To thank all our players who already bought Immune, solved missions will also drop keys from time to time and you'll get much more drops. When Immune turns free, this will change and you'll only be able to get keys by buying them. The price of the keys will also rise.

Unfortunately we had to remove the ingame hat items to implement the new system. But now hats won't be lost if you die, so make sure you collect all the cases, keys and hats before Immune gets free. :)

[*]Hats are Steam Inventory items now! They can be traded, sold, bought or received from cases.
[*]Solving a mission now drops you a case sometimes, which contains one random hat. You can unlock cases with keys.
[*]Solving a mission now drops you a case key sometimes.
[*]Gasmask NPCs carry less powered weapons.
[*]Rebalanced all item drops. Weapons are more rare now. Trash bins and car wrecks drop more but less valuable items.
[*]Added name signs for cities.
[*]Made all trash objects slightly smaller (they were a bit too big).
[*]Made it less likely to get conditions on damage.
[*]Zombies are a tiny bit slower and deal less damage.
[*]Ammo and pill merchants in Hometown have more items in stock.
[*]Zombies and gasmask dudes do not drop raw meat anymore, because cannibalism is silly.
[*]Adjusted sound volumes for sounds like tire squeel, car crash and some others.
[*]Most of the food gives you more energy now.

Thanks again to everyone who supports us and to everyone who bought Immune! You guys are awesome and we will make Immune the best game possible for you.

Let's get some more people into the game, shall we?
