Bentusi Core
saddest part in the game; salvaging parts of an ally. something one must do & promptly as vaygr detected the massive explosion of the bentus.
explosion has caused the bentusi core to break into 3 pieces which u must collect before vaygr forces get them & hyperspace out with them.
this mission's very straight-forward & relatively easy. now according to the mission objectives, u must colect all 3 parts of the core & then kill off all vaygr forces. if u do not want the game to end right after u collect all parts of the core & kill off all vaygr forces, then u should not collect the core pieces first. guard them if u must but first & foremost kill off all vaygr forces, especially the shipyard, 2-3 carriers, a considerable amount of destroyers, the usual fighters & frigates & corvettes & one badass battlecruiser(u can play & replay this game to capture this bad mutha as it's worth every dead marine frigate). & ignore the part where the game asks u to send out a probe. just send your attacking force instead to save time & effort.
when u first arrive at the scene, u'll be near to one of the core pieces. now each of the pieces is covered with some kind of radiation that will destroy any unit, unless u upgrade your defense field frigate. my suggestion is that to send all out to wipe the vaygr but maybe 2-3 flak & torpedo frigates to guard your mutha(ship) & nabaal(shipyard). the dreadnaught is the most powerful unit u have & it can be your tank so use it well. i suggest capital phalanx formation for your attacking force.
move your attacking force to the middle of the map & towards the 2nd nearest core piece. when u're near there, vaygr will hyper into the area & try to get the core pieces. u know what to do with your attacking force.
when that's done, move on to the next patch of enemies & terminate them. naturally u'll meet the vaygr shipyard near the farthest core piece. after killing off all hyperspace-capable vaygr ships, u can rest easy & rebuild your force as well as harvest the much needed resources. collection of the core pieces can be the last thing on your itinerary.
new upgrade: destroyer, defense field frigate
new ship: battlecruiser (very slow build time so u won't get to use them in this mission)
