So I got mechcommander working, just copy the entire CD contents to a folder and then play the game, that easy, no need for installation. I'm running Vista 64bit as well.
On subject, I forgot how amazing this game really is. I remember playing countless hours when it came out so many years ago. I was just playing some of the very first few missions, one I would like to account was OP1: Mission 3.
The mission is to Escort Rven 'Mech to safety. I took a Firestarter-W, two Commando 1-A & 1-W, and a Uller-W. The mission is so fun to be honest.. I used a large air strike on two commando's near the middle of the map, salvaged one and the other went critical. I cut through the forest right there and ran into two commando-J's that jump across and ambush you. I quickly let the Uller to medium distance to open up with his PPC. While the others went close range and tore the first commando to bits.
So the first one down, the Uller takes a shot with its PPC at the second Commando, center torso goes molten and explodes! One shot kill! Was awesome to watch, reminds me so much of the board games!
I regrouped and headed toward the unknown Raven's location. After linking up we made our way around the Island back toward the extraction zone. You run into two Firestarters on the way there which guard a heap of salvage containers, dispatching them quickly I soon moved southward. I captured the little outpost with three laser cannons.
Knowing what came next I selected Hunter in the Commando to do a daring scout. I knew the Madcat/Timberwolf crosses the bridge when a mech approaches. So I sent him to recon, drawing the Clanner out. I had him make a run toward the outpost to allow the madcat to stop, well the AI isn't smart and instead of running around the hill north, he turned around and headed south. I quickly corrected this but too late... ER PPC's and LRM's streaked toward hunter... with two PPC's in the back he ejected safely.
I used the zoom button to locate the cockpit of the madcat. Using a large airstrike, the counter ticked down... BOOOOM! Cockpit cored, battlemech in perfect condition! What a success, Hunter's sacrifice of his commando was worth it! Oh how I recall doing that in the past with the madcat going critical and swearing up and down! I also used to try and hit the fuel tanks right when the madcat came across the bridge, but often it would be destroyed...
I find this old game amazing... it isn't eye candy, but too be honest its unique in its own way. I'm enjoying it yet again, even after so many years from its release.
