That was retarded easy. Don't need a fort, don't need to sleep. Buy a shotgun then an assault rifle. Traps are worthless. Just repair forever and don't worry if you get chewed on a little around round 3ish. Just power through.
Play any other game in the history of games and see that the first spacebar finishes the text typing, and the second clears it. If the first clears it, you can never read it.
This game is just remarkably awful. Such great tech and then such a basic failure of game design principles. Buy a pack of Magic cards and take TWO SECONDS to think about how they balance costs.
