Seems like the devs are pretty strict on not wanting anyone modding the game. On the official Discord server for that game, they have a very strong word of warning about such things. We may want to be careful there.
To ensure a level playing field, we remind players that attempts to hack game files for Marvelís Avengers is against our Terms of Service and is an activity we take extremely seriously, resulting in bans. Please do not use third-party tools to manipulate the game and its data.
