Sadly, we didn't find out much about Hardcore.
Oh, but we did ...
It means it become as DOS as possible:
Explosive projectiles, throwable explosives, explosive mines hidden all around, explosive barrels prepared to (you guested it) explode to your face ...
I mean, in games, i like to let my inner pyromaniac loose as much as any other ... but this seemed a bit too much even for me.
I mean (again i know).
Its not a bad desing per se ... yes, we know that goblins are buying tons of explosives, so it make sense that they intend to use them ... yes, it makes sense that Goblins will prepare the ambush properly ... yes, those barrels can be seen ... and most likely yes, you will be able to stuff them in your pocket, wich would perfectly cancel almost any difficiulty it would add.
Still, it feels kinda lazy, doesnt it?
"Hey, we need to make this fight harder! > Got ya! No problem ... add explosives."
I mean ... just ugh. :-/
