For this mission speed is of the essence.

Quickly group all you bikers together. Then group all the other stuff. Send the bikers down. Select the second group and send them to the visible area to the left that is below the cliff that they are on. This is just to get them on the right path of travel.

Go back to the bikers. Have them ignore anything that they come across. Pretty soon they will come to a road but you can't get on it here because it is blocked. This is the road the tankers are on. Keep sending the bikers along until you come to a split in the path that have been following. Go up. Get on the road and follow it until you catch the tankers. You should also change the path of the second group to put them on the road with the tankers.

Now! Get the bikes in front of the first tanker so you can block its path. Target it with the bikes and have them kill it. Have the second group target the second tanker. Try to keep the bikers alive so that you can use them to block the path of the other tankers.

You areadly know my name but I would like to tell you some of my strategies (I also want to tell you that I don't have the demo or the game.)

In the start the first thing to do is select all your units and group them.

Send them all down and tell them all to attack the little car down there. When hese dead continue down and kill the next little unit them go west as soon as possible when you can go up squeeze between the first building and the wall and send all your units through there as soon as you see the ATV attack and kill it, then continue to follow the first truk you will come across a barrage craft kill it with all youv'e got when it's dead go on to follow the fist truck in the convoy (make sure you get the FIRST truck) and blow it to HELL. You Should be able to kill it before it reaches the five guys and the tank. After it's dead turn back and kill the rest.

I've finished this mission at least four times 'coz of some batch files I made deleted my save game files.

By now, your Alchemy Hall should be complete. Upgrade your Beast enclosure first and then Clan Hall. Don't bother to upgrade the Blacksmith or build towers. Put War Mastadons and Pyromaniacs on infinite. Once you have 10 or so War Mastadons, stop training pyros. By now, you should be low on oil. Build another derrick and send it to the northwestern to the oil patch and take a War Mastadon and destroy the unrepaired power station. Then build two power stations as close to your western rig as posible. Move your tankers over to this rig and use your new power stations.

By now, you should have repelled a lot of attacks, but found out that they have not attacked with a large enough force to kill you because of your War Mastadons. Once you have 30 or so War Mastadons, send them after one of the enemy retreats. This way, they will have little to destroy you, except for his turrets. Try and destroy any turrets that attack you, but make it a priority to destroy his tankers, rigs, and power stations respectively.
