Good ideas and poor execution is the shortest way to describe this title.
Taking core ideas from both traditional RTS and mech games, Mechs & Mercs: Black Talons failed to find a good balance and mixture between the two genres and ended up being a severely unbalanced game. Described as a tactical RTS with various unit types that each have their own strengths and weaknesses, the vast superiority of certain units, such as heavily armored ones, causes the player to disregard any tactical approach whatsoever and apply brute force to power their way through the levels.
The imbalance is further exaggerated by the easily exploitable leveling and XP systems thanks to the constant spawning of enemy units who will just mindlessly charge against you. This allows players to simply farm XP and obtain levels that should not have been attained so early in the game.
