" 18. Columbia
OBJECTIVES: -Provide your base with 100,000 CR
TRANSPORT: Harvester x3, Gargoyle x4, <Tiger> x3
RESEARCH: no new advances
ENEMIES: LC in the southwest, ED in the southeast. Look for 20mm Meteors and
Groznys; Sonic Thunderers; 120mm, Ion, and Laser Kruszchevs and Urals; and
20mm, Rocket, and Electro Lunars and Moons.
MISSION: Just like the Andes, only easier. You'll have to use Energy
Transmitters to reach the field east of your base, but again that won't be
enough to fulfill the objective. Throw up a few rocket defenses around the
Power Plant just in case. You get another free Grizzly and some Plasma
Panthers and Rocket Spiders for defense.
The LC will send a medium-sized tank force at you early in the mission so
make sure you have enough combat units in the Albatross to deal with it. The
starting units won't be enough on their own. Expect LC and ED tanks from the
south, LC air units from the west, and ED air units from the east. Tanks will
have to drive past the central mineral field to reach you base, allowing you
to engage them away from the main base. You'll also see a large-scale raid by
Thunderers that can be quite destructive, but after that the LC runs out of
minerals.
Send the Gargoyles to map center to secure the large field. I don't
recommend trying to attack either of the enemy bases because they start
entrenched and the mineral facilities are on the far sides. Mining this field
will be necessary and you can get a start by bringing in three more Harvesters
and setting up a satellite mining operation while the first field is still
running. Put up Towers if absolutely necessary."
IIRC meteors are the LC superweapon, so kill their weather control thing and there you go.
Hey, that game brings back memories !
If i remember there were some missions on the moon, or i am completely confusing it with some other game.
Could be a BrainSlug.
Do not remember that mission, but i guess maybe some shield strategy would help.
lol
There was an expansion called "The Moon Project", i think some of it was on the moon yeah.
I loved that game, online was populated by germans who rushed with minelayers though
My 3 or 4 tanks were no match for a few hundred minelayers with the little machine gun fitted on top :awe:
