Ardent Seas blends modern naval combat with classical RTS gameplay, featuring Aliens, space lasers, and unholy amounts of missiles
CIWS are getting some changes overall.
Previously it was the case that TDN ships only had SeaRAM-type defensive missile launchers. Now, TDN ships mostly use these guns, and 1-2 RAM launchers if any.
The CIWS guns fire more quickly than the Missile launchers, and can engage new incoming missiles as quickly as they can kill them. The CIWS Missile launchers in turn, have greater range, but fire more slowly.
The Gun-based CIWS systems now receive the Laser upgrade, while the Missile based systems will likely get a range or rate of fire upgrade.
One positive side-effect is that it also makes battles look a little more lively :P
