You are playing Flagstaff Chapter 4 hacked and unblocked by BlessFlasher.com.
The turn-based adventures continue in the fourth installment of Flagstaff. Like the previous chapters, you control the actions of five characters as they face various enemies. Each character is allowed to move a certain number spaces and can only use an ability once per turn.
However, you can upgrade characters to increase the number of moves/abilities allowed. At the start of the game, you're given a bunch of upgrade points to improve your characters' skills. Spend them wisely!
