ПХБ ДнД 3.5

Написано, довольно противоречиво:

Step 2
Opponent Avoids? The defender has the option to simply avoid you. If he avoids you, he doesn’t suffer any ill effect . If you were attempting the overrun as a part of charge,you may keep moving (you can always move through a square occupied by someone, who lets you by). In either case, the overrun attempt doesnt count against your actions in this round (except for any movement required to enter the opponents square)

Step 3
Opponent Blocks? If your opponent blocks you, make a Strength check opposed by the defender’s Dexterity or Strength check (whichever ability score has the higher modifier). A combatant gets a +4 bonus on the check for every size category he is larger than Medium or a –4 penalty for every size category he is smaller than Medium. The defender gets a +4 bonus on his check if he has more than two legs or is otherwise more stable than a normal humanoid. If you win, you knock the defender prone. If you lose, the defender may immediately react and make a Strength check opposed by your Dexterity or Strength check (including the size modifiers noted above, but no other modifiers) to try to knock you prone.

Step 4
Consequences. If you succeed in knocking your opponent prone, you can continue your movement as normal. If you fail and are knocked prone in turn, you have to move 5 feet back the way you came and fall prone, ending your movement there. If you fail but are not knocked prone, you have to move 5 feet back the way you came, ending your movement there. If that square is occupied, you fall prone in that square.

то есть теоритически, можно пройти первого противника (он уступает), второго (допустим сбил), а третьего уже не собъешь - ты можешь куда-то пойти на 5 футов. Но если коридор всего 5 футов, сзади орк, спереди орк, которого уже сбить не сможешь и под тобой лежит орк, то куда отходить то?
