We’ve got four distinct Evil Geniuses and, while each of them is tailored to a different play style, they do have some things in common. For example, they’re need to be protected. Yes, that includes Red Ivan, who might be hardier than the others, but he’s still at risk of being overwhelmed by some well-trained Agents. Keep them protected by minions at all times, and ensure that you send others to do your fighting.
Of course, all of our Geniuses are available at the start of the game, but it’s worth re-iterating that you can pick whoever you like. Each Genius has some key differences between them, but don’t take their advantages as guidance for your play style – you can still play Evil Genius the way you want, despite each of our Characters’ strengths and weaknesses.
