Well I’ve made it to day 23, and it looks like I’ve maxed out everything. I know I’ve maxed out my weapon upgrades they say ‘ max ‘, and blocks ( at 75 ) and traps ( at 25 ) and gunmen ( at 8 ) haven’t increased for a few turns. This, so far, has been the farthest I’ve gotten on this game. If I don’t get more increases after this round I suspect my days are numbered. The Zombies keep getting stronger and more plentiful but my ability to fend then off hasn’t. We shall see if I live long enough to see day 24, but I suspect I’m a goner.
