SPOILER - WALKTHROUGH

- Open all the windows and turn the red arrow around.
- Open the hatch on the right, click the yellow arrow to get a man out.
- Fire one round in the low position to drop the bridge down.
- Fire the second round up at the bell and click the spike thingy so it goes the other way JUST after the round hits the bell (you do NOT want the round to alter the direction of the spike)
- Fire the next two rounds at the bridge - they are explosives - but click the bridge to knock them in the air and explode without causing damage.
- Click the lightbulb by the dude at the bottom to get him to smash it.
- Fire the last round in the low position, and the bottom guy picks it up and opens the door with it.
- Now click the dude by the machine so he gets in it, and click the yellow arrow to get another guy out - then get him to fire the other dude up at the bell.
- The man by the bell will move the tower over if you click him. Then click the spike thing. Now keep clicking the bell till it falls.  No more land mine.
- Click the door in the bottom left so the guy comes out and JUST as he goes in the door on the right, click the bottom man. A dog tries to chase him, but the falling concrete stops it.
