About Battle Academy Operation Sealion
Battle Academy Operation Sealion is an add-on for Battle Academy set during a fictional German invasion of Britain in September 1940. You command the Home Guard in counterattacks against German glider troops and in the defence of the South Coast Sea Front. Missions also send you on clandestine “Butcher and Bolt” operations with the Auxiliary Units or let you land coastal raiders from Motor Gun Boats.
Single-player missions
The campaign contains ten varied single-player missions. Silent-kill attacks support clandestine stealth operations, while naval units can transport raiders around coastal maps.
British units
The add-on introduces Homeguard, Sticky Bombers, a Guy Armoured Car, a MkVI Light Tank, A10 and A13 Cruiser tanks, a 4inch Gun Lorry, an Armadillo Armoured truck, a Boyes Rifle Carrier, Auxilliary Unit Commandos and snipers, and Motor Gun Boats.
1940s Britain
The terrain and buildings use a new 1940s British set, including red postboxes and telephone kiosks. Battle Academy is required to play the add-on.
