The guns are pretty much worthless. Zombies are really op. Sure you can kite them, but that just inst fun, yet its the only way to kill them.
PvP is stuff tier. Everybody is hostile and since you lose all experience on death, it becomes hard to survive against high level people.
Building a house is worthless because zombies will ALWAYS attack it, and a wood house takes quite some time to make, and is destroyed easily.
You depend on random spawning to live, which could mean you can find a fire ax, but not a normal ax, so you cant cut wood in the crafting.
On that no, it could take a long time to find a pickaxe.
I have reasons for not liking the game. Its fun for a little bit, but only for a little bit.
