Found a couple more typos (bolded them),
Mobile Builder
Allows you to build economic and defensive ships at planets your team doesn't control. Cruicial for establishing beachheads in enemy or neutral territory
Cruicial should be Crucial
Siege Starship
This is not so much a ship as a gun with engines on it. It is expensive, slow, thinly armored, has a low rate-of-fire, and can't even fire upon most small mobile targets. Also, many targets (forcefields, most fortresses and command stations, etc) are specifically protected against the Siege's antimatter bombs. Butit CAN hit and do grievous harm to starships, guard posts, guardians, and most turrets.
Butit lost its space.
