Am I missing something with the faction heritage upgrades? 5,000 faction coins is rather steep for a relatively small bonus. Do purchased FH upgrades remain purchased across games, rather than simply unlocked?
High difficulty levels should unlock all the medals of low difficulty levels. For example, if I finish level one on Ace, I should receive the medals for Rookie and Veteran as well.
A tip for the hard badge: Level 19 is largely luck based. Don't get discouraged if you get many difficult bosses the first time. Also, stay away from the top of the screen, especially when the music begins to fade out.
Word of advice: the scrolls include the player as a friendly unit. They're more useful than medium potions once the player has >900 hp, and more cost effective so long as they have >150.
It would be interesting if foreign countries reacted to what the player did. For example, if the player was invading a lot of nations, NATO or some other alliance would get angry at them and do something to weaken the player. International arms deals could weaken these alliances and result in the player being able to invade more effectively.
Just got the hard badge. The trick is to use the BFG, the energy homers, and the duck, firing the first and last of them whenever they're ready and using the homers while both cool down.
Beat the game. Still not sure what all of the letters mean. The Gs seem to be predators, and everything but the walls and the blue {s will kill the player if they step on them. The Xs are corpses, which will satisfy the Gs, keeping them still until the end of the level.
