Level 4 security mission.
Enemy type: Rogue drones, mercenaries (thermal/kinetic from drones, explosive from mercs?)
Nothing can hit when out at 150km+. Easy sniping in Level 4 Mission Sentry Dominix. Also easily done with Level 4 Mission Pulse Apocalypse.
Warpin
Only an acceleration gate.
Room 1
Enemies at 50km. Two towers that aggro on warp-in. Enemies do not aggro though. Could slowboat away. Enemies aggro when shooting towers. Many battleships that do heavy damage (thermal/kinetic).
Room 2
Enemies 20-90km away. In three distinct groups. They did not aggro right away. Could slowboat to some distance then engage each group as necessary.
Room 3
Third room lots of towers, can kill boss and Road House building and ignore towers.
