Megalodon is extremely overpowered, definitely need to be balanced with next update. Same is for Swordfish, it is twice more powerful compared to other factions navy units and the cherry on top of the cake is that it has Anti-Air also.. It would be good to make separate anti-air navy unit in order Swordfish to remain ground only.
Greetz again and admirations for all the work you have done so far. I am looking forward to new update and it's a great thing that navy will be expanded. Also it would be awesome if you add 'Tesla boat' for Soviet navy
