I went through about 20 weapons before I found the one that worked best for me. I thought it was great because it was the only real roadblock where you really had to grind survival to find and upgrade the weapons that can lead you to finishing the game. One thing that seems to bother lots of people is the Titan fight is very difficult.
This special edition got rid of all the kinks that bothered me about the original. Plus the fact that upgrades don’t have the angering timer makes it so you can constantly progress and get through a province in a matter of hours instead of days or even weeks. This game has many gems and unlimited energy that leads to much faster progression. I didn’t feel the need to buy unlimited for so much money. I had already played the regular game for a long time and couldn’t get near the end because of the energy limit.
