No, why don't you download some replays and try it out
1) Logon to any bnet server
2) Load up the replay file (alt+tab and hit open replay in War2Insight, then click view replay)
3) Create a game, select the map the game was played on, set game type as Meele and tick Fixed Positions (and set a game password)
4) Set the exact number of "computer opponents" listed at bottom of the War2Insight window, this changes per replay depending on the number of players.
5) Start the game.
