You control a handful of LOTR characters.
During phase 1 everybody gets to select a square to move to. Then everybody moves at once. If the opposition gets close the movement stops.
During phase 2 everybody gets the chance to use an attack or item.
Each mission is very LOTR with scenes throughout the films.
Phase 1 can be a little cat and mouse. Trying to keep the tougher hand to hand characters in the way whilst trying to keep the ranged at distance.
Phase 2 is a very standard turn based attack style.
The game works quite well. It starts off carefully balanced keeping the fight on a knife edge between success and failure. Unfortunately the game became difficult part way through and I had to grind the first level (which can be completed in 2 turns) to improve my characters abilities. Completing a level gives around enough money to purchase a stat increase such as +2 to strength. The game then went back to being challenging until near the end where my characters had become overly powerful and careful tactics became unnecessary. .
There's the problem. The game is a slow and tactical with a balanced difficulty. Until the level difficulty is second guessing on how powerful your characters abilities are, and the game loses it's balance.
