The devs on Deus Ex: Invisible War knew its most-hated part was a 'terrible idea,' and they give the director 'sh*t about it all the time'
For nearly four years, my author bio on this website has informed you that Deus Ex: Invisible War was pretty good, actually. The much-maligned sequel to one of the greatest games of all time had its flaws in spades, I don't deny that, but it kept enough of a beating imsim heart that my 13-year-old self fell in love with it nonetheless.
One thing I can't argue with: universal ammo sucked. If you've not played IW, it had a some-would-say innovative system that meant every weapon in your inventory shared the same pool.
