首先找到\My Documents\My Games\Gears of War for Windows\WarGame\Config里的WarInput.ini，记得先备份，用notepad打开，查找
[Engine.Console]
然后把相应的代码改成下面那样
ConsoleKey=Tilde
TypeKey=Tilde
MaxScrollbackSize=1024
HistoryBot=-1
bEnableUI=True
保存后进游戏，按～打开控制台，输入以下相应的作弊码
手雷弹药量 set WarfareGame.Weap_Grenade magsize
机枪弹药量 set WarfareGame.Weap_AssaultRifle magsize
手炮弹药量 set warfaregame.weap_locustpistol magsize
兽人机枪弹药量 set warfaregame.weap_locustassaultrifle magsize
霰弹弹药量 set warfaregame.weap_shotgun magsize
阻击弹药量 set WarfareGame.Weap_SniperRifle magsize
手枪弹药量 set warfaregame.weap_cogpistol magsize
弓箭弹药量 set WarfareGameContentWeapons.Weap_Bow magsize
Baird血量 set WarfareGameContent.Pawn_COGBaird DefaultHealth <number>
Carmine血量 set WarfareGameContent.Pawn_COGCarmine DefaultHealth <number>
Cole血量 set WarfareGameContent.Pawn_COGGus DefaultHealth <number>
Dom血量 set WarfareGame.Pawn_COGDom DefaultHealth <number>
Marcus血量 set WarfareGame.Pawn_COGMarcus DefaultHealth <number>
Minh血量 set WarfareGameContent.Pawn_COGMinh DefaultHealth <number>
把<number>改成你想要的数字就可以了。
更简单的方法是在\My Documents\My Games\Gears of War for Windows\Binaries里面生成一个文本文件，比如cheat.txt，把你想开的作弊码写进去，比如下面那样
set WarfareGame.Weap_Grenade magsize 9999
set WarfareGame.Weap_AssaultRifle magsize 9999
set warfaregame.weap_locustpistol magsize 9999
set warfaregame.weap_locustassaultrifle magsize 9999
set warfaregame.weap_shotgun magsize 9999
set WarfareGame.Weap_SniperRifle magsize 9999
set warfaregame.weap_cogpistol magsize 9999
set WarfareGameContentWeapons.Weap_Bow magsize 9999
set WarfareGame.Pawn_COGMarcus DefaultHealth 99999
