I don't know if the trainer needs updated or not. The game crashes when loading into a mission with the unlimited Energy, AP and Ammo activated. As for the Change Credits and WXP neither work, I followed the directions under the info tab to use them and neither worked. I understand that this an early access game so keeping up on the trainer can take time. I just wanted to point out the issues I am having.
While the trainer does need an update, we don't really need one as of right now. Game is in pre Alpha. I've been using Cosmos to very easily change up the credits, simply open up beginner mode (make sure you have three or four items to sell first). Enter in your current credits value and search, then tab back to game, sell one item and redo the search. Do this two or three times until there are only two values being found.
I only changed the first value. Leave the second alone. Game allows you to have 100mil credits in total.
None of the other trainer options are required currently as having the boosts that drop will allow you to fight with one mech indefinitely. Great game even though its only three missions. Can't wait for them to release more missions and mech's as they have plenty of mechs and equipment in development. 😁
