100 days?
i can beat that easily
Hell, ive racked up quite a few 80-88 day patrol in an IXC (although i was sucking fumes when i pulled into lorient). So im pretty sure i can do well over 100 days in an IXD2. Ive got me a new challenge in this game.
waste gate,
Yeah i suppose you need a fair ammount of patience for an IX boat. Long transits, and constant submerge/surface routines can be tedious.
