Touch Arcade:
What started as a promotion to keep people playing Eliminate in the wake of the massive worldwide release of Modern Warfare 2 has now been extended "until further notice". If you haven't fired up the game recently, the rate at which energy recharges has been reduced to 60 minutes, down from 240.
Because of this change, players will be energized more often, earn more credits, and in turn be able to spend those credits on the various upgrades that are sold in game much faster. If this somehow is the first time you've heard of Eliminate, if you're at all interested in first person shooters you should download it (for free) as soon as you can.
