So... after a few days of dwelling into flash games I have to resist linking everything that kept me entertained for more than a few hours.. so let's just pick the one that gave me the most laughter.
As an evil genius, plot with your cronies to reach the ultimate goal - to destroy the World! The game is a bit simple and easy after you get a hang of it, but since it's full with voice-acted ever changing flash cut-scenes with hilarious dialogues, I kept doing a lot of unnecessary stuff just to see my minions act.
'A good night everyone, and a safe drive home.'
'ALL HAIL THE MASTERMIND!'
It's flashy, but why not multiplayer? This game begs for it. I rather play TDP4. It's only problem is the pay or grind system. But if you are rich or patient, it's a perfect shooter.
