Answer 3

In a network game, you can "cheat" only on what the server is given at the mercy of the client.
If, for example, health is controlled on the server, nothing can be done.
It all depends on the specific game. There are developers who fiercely wield a banhammer for even a suspicion of a cheat, but there are those who don’t give a damn.
In shooting games, you can make aim-bota, for example, so that each bullet flies into the enemy’s head (even if you shoot with your back to him), map hacking is popular in strategies - when the entire map (and enemy units) become visible, etc.
If the game offline - everything is allowed here. We climb into the memory of the process and modify whatever our heart desires.
