Welcome to the community.
WeMod is a law-abiding company and does not condone criminal acts, such as the theft of intellectual property, including digital games.
We do not deliberately make trainers to work with illegal versions of games. And we do not provide any support for illegal versions of games.
Understandably the price tag of this game in stores is a little too high for some people. However, this game is under $10 on legal key selling websites such as https://www.cdkeys.com/assassins-creed-odyssey-pc-uplay-cd-key. Therefore you have no excuse to not buy the game to support the developers.
On top of this, cracked games are not as free as you think they are, even the criminals cracking these games need to earn money somehow. They are bundled with spyware, trackers, and also crypto miners. Crypto miners in particular will cause your electricity bill to spike and end up costing you more than it would have cost you to buy the game properly. Anti-viruses do not scan for crypto miners.
