[PC][2005-2010]FPS singleplayer game, you could choose your loadout before mission and also customize your robot (or titan like in titanfall) i think, the first mission was on a snow map

This is a tough one because i barely remember anything about the game, but i remember my friend brought a cd with it and installed it on my pc, the game was singleplayer, you could choose your weapons before the start of any missions, also you could customize your robot/titan and choose some perks i guess? the first mission was happening on a snow map, that's all i remember.
