I'm a big fan of BLAME!, so I am really glad I found this. Aspects and Contamination Die are very cool. I really like opponents being represent as a puzzle to bypass their defense. I have not seen any other 24xx hack that did this. Thanks for the game!

the only ones I've looked at are Blam! v0.6 (https://rpggeek.com/rpgitem/301164/blam) and Evolution Pulse (a FATE based game, https://rpggeek.com/rpgitem/173168/evolution-pulse ) is pretty close. Blam! is good for mining ideas - quite crunchy. I've not really looked at EP in any detail.
