Why Mars War Logs does not have the trainer, i mean MrAntiFun which is your partner already created trainer for this game ( Mars War Logs Trainer | MrAntiFun, PC Video Game Trainers, Cheats and mods ).
Hello! 
MrAntiFun is periodically porting some of his trainers here to WeMod. However, as he has thousands of them and still needs to build new ones or update his existing ones here, this is going to take a very long time.
As such, he will be focusing on games that still have a decent player base here in the WeMod community. The WeMod software automatically detects how many members actively play each game.
This game was released in 2013, so it’s likely that the majority of the playerbase has moved on, hence it likely isn’t a priority for MAF to port that trainer here right now.
