I hope I'm not the only one who counts Ironclaw Munitions Factory as his favorite level in the game. I love having half the level be puzzle/coordination hazards as opposed to straight combat, weaving between rockets and using cover as needed. Also, the Twins are the most fun boss fight I've experienced in a long time.
There's one problem though: Nobody ever wants to run IMF. Not just because it's more difficult than the Royal Jelly Palace, but because the payout is so much smaller. A full RJP run via the mission nets approximately 3000 crowns, plus the jelly gems that can be traded in for the antigua and/or sealed sword, two of the most popular upgrade paths in the game. An Ironclaw run, on the other hand, costs the same energy (possibly more because it's harder -- revives, etc.) but only serves 2000 crowns if one is lucky. The lack of enemy numbers also means less materials drop. Finally, the boss token rewards are fairly lame aside from the Pulsar and maybe a Static Capacitor for bomb specs.
I would love to have more loot involved with Ironclaw Munitions Factory so people no longer think of it as a chore that's a bad economic choice. I hope I get others to support this -- it's a fun, smartly designed level that's different from anything in the game.
*reads title* Great, another person asking for a ner... Oh wait, this one's not bad :D
+1 to bring the CR/Heat output to ~= RJP.
It is a bit harder tbh, and should give around the same rewards as RJP. The main reason why the CR/Heat discrepancy exists is because where RJP spawns enemies, IMF has traps. One gives rewards, one doesn't :/
Also, you didn't say it explicitly, but it seems you were hinting about the value of the IMF tokens being raised somehow. Don't touch them.
