Yea "Aussie Rules" is impossible
I have the 360 version, haven't tried that cheat but I assume it doesn't work on 360 either. I've beaten all of the other challenges (a few practically require you "stack" the lineups ahead of time). I've been playing "Aussie Rules" for the past 3 days, for about 5 hours each day, and the best I've done is get 6 goals two times. Both times it was because the other team got a red card and I just did through balls past their crappy defenders.
My biggest qualm is the quality of the goalkeeper. I swear, they rigged something for this match, the stats of that keeper are horrendous, yet he stops nearly every shot i throw at him. It is absolutely insane.
So far I've been most successful with the following settings:
Australia formation: 1-4-3-2
lineup (reading from the top down, minus the GK's):
australia:
1-4-3-2
moore
chipperfield
emerton
neill
Tiatto
bresciano
viduka
thompson
cahill
kewell
Offensive tactic: counter-attack
Defensive tactic: pressing the ball
Solomon Islands:
4-3-3
Billy
Konofilia
G. Abba
J. Molea
P. Boe
M. Ruhasia
G. Omokirio
G. Suri
B. Suri
M. Houkarawa
The only way I've scored goals is by doing through balls, their defenders are terrible and you can easily outrun them. Viduka is probably the best finisher for australia, but he's way too slow and can't sneak past the offsides trap as well as the other guys. related to this, for a while i tried having bresciano and tiatto as the forwards as they're the fastest on the team. but their finishing skills are not that great, and like I said, this goalie is so amazingly good.
If anyone else has any advice or hints, I'd love to hear them. This game is driving me nuts!!
