Lode Runner was released on XBLA back on April 22nd, 2009, but was met with middling success. I would assume that those of you who did purchase the game will have thought that you had finished it a while ago. You were wrong; nearly two years after the game was released, the first of two pieces of DLC has been released. The "Skill Expansion Pack" DLC comes with one additional achievement worth 15G.
Play and post scores on 8 new Hang On levels, and solve a slew of new master puzzles! Professional Lode Runners needed!"Skill Expansion Pack" costs 160 MSP and can be downloaded from here.
As I mentioned above, a second piece of DLC will also be arriving for the game. The "Journey Expansion Pack" will cost 240 MSP and is due to be released on April 13th. It will add two achievements worth a total of 35G.
It may also be worth noting that Lode Runner has received a permanent price discount. The game now costs only 800 MSP, down from its initial price of 1200 MSP. The game can be downloaded from here.
