Exercising a little patience can top up your resources, avoiding the micro-transaction system. Exiting and re-entering a specific room causes the glitch, which spawns a random resource.
Sometimes it will spawn a health or stasis pack which can be sold to buy more resources. It's certainly an 'egg on face' moment for EA and Visceral Games.
However it should be noted that EA and Dead Space 3's development team have said the reason they have this 'controversial' micro-transaction system in place is to providethat are used to spending a little more of their money to 'skip' certain elements of a game - like resource gathering or level progression.
The micro-transaction system also supports an in-game currency which can be scavenged. These resources are necessary in upgrading player suits and putting together improved weapons to tackle the Necromorphs.
Dead Space 3 releases on Xbox 360, PS3 and PC this Friday in Europe.
