I agree. Please add infinite health if anything, because gold can be done through independently using Cheat Engine 4 byte values. A way I've found to do the health is this:
The default squad size is 9 including the leader, so 8 soldiers. The starting value is 8, changing it using 4 byte can make it go to 0 and can mess up the formations of approaching raiders. With a maxed ring of command (Increases squad size to 16) the value is 15 for soldiers. I cannot find the health value, and I have not been able to find the campaign save through datamining to find references to values and resource sets.
So, if a trainer is added, I'd say infinite health is a No. 1 priority. Through infinite health you don't really need the gold. Anyways, please make the trainer as fast as you can, and keep up the good work MrAntiFun!
