BASHER
The basher digs a horizontal tunnel through walls. Bashers cannot bash through steel or against one-way brick.

BLOCKER
The blocker is useful to block off areas that you want to keep the Lemmings away from (or areas that you made mistakes on) The blocker is also useful to explode walls with exact areas. If you want to unblock a blocker, you must clear the ground below it (Miner then Builder is the best way).

BUILDER
The builder builds stairlike platforms. It is useful for crossing gaps. They run out of bricks after a while, however, and walk right on- dangerous if the bridge does not completely span the gap.

CLIMBER
The climber has the ability to scale walls and cliffs. They are most useful when also Floaters. When also Floaters, Climbers are called Athletes.

DIGGER
The digger digs a vertical hole in the ground, but not through steel. Be careful, because if you dig from a high elevation and the Lemmings fall through, they may be killed. (This does not apply to Floaters- see below.)

EXPLODER
The exploder is useful to clear areas when you don't have any Diggers, Miners, or Bashers. It will walk around with a countdown. When the countdown reaches 0, the Lemming explodes, and takes out the area around it. To explode the location you want, you can either try get the 5-second timing right (easier said than done), or make the lemming a blocker first. Exploders can clear one way brick, but not steel.

FLOATER
Floaters have the ability to parachute down long distances. If a regular lemming falls from a long distance, it will die, but a Floater will stay alive. When also Climbers, Floaters are called Athletes.

MINER
The miner digs a hole in the ground in a diagonal direction. Miners cannot mine through steel or against one-way brick.
