Team17 did say it was shaking things up in Worms Revolution, after making largely the same game for 17 years, and it seems that may be the case. Worms Rev will introduce classes to the turn-based strategy series, the English indie has revealed, in four flavours with different attributes and abilties.

The Soldier class is the plain old regular worm as seen in countless games, but it's joined by the Scout and Heavy classes. They have less or more attack power and are lighter or heavier, respectively, so they trade off damage for mobility and vulnerability to being buffeted around.

The fourth class, the Scientist, is something of a support role. Scientists are weaker and slower than Soldiers, but automatically heal their chums every turn and can equip gear like the Sentry Guns and Electromagnets.

Worms Rev is crawling onto PC and some form of console between July and September. Series creator Andy Davidson recently rejoined Team17 to chip in, after over a decade away.
