What's about a really hardcore mode for the game? Like an ultimative challenge for real guardians? I think something like a special mission like prison of elders but in better. If we take a look about Warframe it would be cool and hard if we get a Survival Mode in Waves. With every Wave we get more negative Modifiers (AND ONLY THEM!). If we reach the final wave the iron modifier from Halo will be add but with a small change on the function... You can die one time with the possibility to get revived by allies, after that the Mission will fail if ANYONE of your team dies again. It would be a real challenge with all these modifiers active... And don't get me wrong, Burn Modifiers will not work for our abilites and weapons! I think this would be a fair challenge for really rare items and loot like exotics which can only found in this mission. But what do you think? Would you like to see this ordeal?
