This was EXTREMELY easy but very well done. The graphics are excellent, the weapons are even better (Wow, the Barrett was great!), but I found that it was so easy because if you spend 6 on Weapons and 6 on Survivors for the first couple days, you can get all the survivors and at least 1 automatic weapon. Once you have all your survivors you pump your hours into weapons and you can get the more powerful weapons. I didn't repair my barrier from day 8 until I beat it. Other than that this game is perfect. The only thing you can do in a next version is add more weapons, more survivors, and more days!
