About trading cards
Hello everyone! For the past couple of months people complained about steam trading cards not dropping, even though I added them to the game a long time ago. After checking everything I saw that cards indeed not dropping for anybody.
I contacted valve to solve this issue, now we just need to wait some time for them to look into it. Thank you for your patience

Early Access version 0.7a
New update was just released:
There was an issue, that survivor enemies on the first level were too strong to fight. It is now fixed.
Enemies spawn now from single random spawn point on map, instead of all points together.
New map mechanic added - Infection level. It is similiar to rebel fleet in FTL - a giant horde of zombies, coming from left corner of the map to the right. It's not really that aggressive and it gives plenty of time to explore the map, it only prevents players from wandering the whole map and each event aimlessly.
A couple of new events added to the first level
Early Access version 0.6a
new version just added to the game. Survival mode is now playable. You can fight against waves of zombies, create and equip your team, buy defensive structures. Right now you just completing waves, but later after steam cloud integration, there will be high score table between all players.
