nope In the "multi-player focused Tactics Mode" players will take "control of their very own Secret Island Base made up of many different islands, each island imparting a tactical advantage for the player to use at the beginning of a game."
For example, the player could recon a battlefield before the war commences, or snipe an enemy worm to gain the upper hand; each one of the 16 islands available in game can be used to compliment the player's individual play style. Take the fight online and, should you be victorious, you will have the opportunity to steal an item from your opponent's island for your own personal use!
Much like the Wii version, the PSP SKU of Battle Islands will also include worm and weapon customization. The PSP version will get "an exclusive 'Time Attack' mode, comprised of ten individual time-based single-player challenges.
