Quick question , does tier 4 open up in the game or is locked , i cant seem to get it working. I can upgrade everything barr that.
Tier 4?
Sorry i meant the tech level , when i place a research building it opens up tech level one and i can upgrade when i do the second research building i can do turrets etc .
At this moment the game only have 3 tech levels, for you to get the 3 tech levels you need to build Research structures, 1 per tech level. max of 3.
yeah that was my question , i have done all 3 tech levels just wondering about 4 , thanks for clearing that up for me .
