For those of you who want to spruce up your Battleship experience, EA has included two different versions of the game: Salvo and Superweapons.
Salvo mode lets you select as many squares on the grid as you have ships remaining. Originally everyone can select five grid squares. However, if you have, say, three ships remaining, you will only be able to select three spaces. It's an interesting variant, although it seems to unfairly penalize the losing party.
Superweapons mode gives everyone new weapons. Although these are given cool names like "Air Strike" and "Frag Bomb", they really just represent a sequence of grid squares. So, for example, the Air Strike weapon lets you target five consecutive squares in a row or column. Each weapon has a unique recharge time before it can be used again, to prevent spamming the best attacks.
