Mechstermination Force feels like it comes very close to having a manageable learning curve. Quality-wise, it's great, and a good homage to its boss-filled predecessors. However, there's nothing more game-ruining than, you know, not being able to play the game. There's hard, and then there's hard hard, and then there's Mechstermination Force. It can be done. It can be beaten. I just hope you have a spare hour or two for every boss, and some throat lozenges and ice water nearby.
