The disposal team has discovered a strange transmission after the artefacts on site one were destroyed. Was this discovery meaningless, or could the artefacts hold a greater secret? Site two might just have the answer. The level of challenge has grown. Fifteen stages will have to be cleared as part of site two. Intelligence suggests that the artefacts found there have regenerative capabilities. Due to these circumstances, central command has issued a software update to all units. Your power-ups will now recharge over time. Make good use of this.
