First start game world and select any Mech of yours then activate the cheat , Now de-select the Mech by pressing Esc on keyboard or select another Mech and switch back , Every Mech you select which belongs to you will have super health and armor , It won't effect enemy Mechs .
First end a Mech turn then activate Heat and Stability cheats
First go into the shop and buy anything , Then activate Free Shop Items cheat then buy any item again and it will add that item value to your budget instead of subtracting it .
sometimes you need to try again , or restart all over. but it works for me. dont have urban dlc.
