Mechanical Commando 2
Controls: Use 'wasd' or arrow keys to move. Press left mouse click to shoot or press space for shoulder weapons (missile launcher). Press 'o' to read options, map, objectives.
HINT: If you shoot very close to the wall, the bullets penetrate the wall and hit the enemy on the other side.
Lacks: Some enemies are just too strong. It had also happened that the game slows down or gets stuck. It is not an original one. There are many sci-fi RPG games like this one.
Despite numerous glitches, this is one of the best mech games out there. Most of the players would love to see Mechanical Commando 3 some time soon.
