There is a way to get your save back, if you've beaten this before the badges. If you go to C:\Users\YOURNAME\AppData\Roaming\Macromedia\Flash Player\#SharedObjects\RANDOMNUMBER\chat.kongregate.com\gamez\0008\1947\live you should see two folders, each with a save inside. Replace the smaller .sol file with the larger one and then load up the game and look at your achievements. Should work :)
Haha, I like the allusions to other popular Flash games, like the animation of the knight (Knight's Story) attacking the hedgehog (Hedgehog Launch) in the background. Nice game, CTSG :)
Great start! I'm loving the gameplay and graphics, and the smoke and particle effects from the weapons are top notch. Add some more levels! :) Also, you could consider doing a "Survival Mode" of sorts where the player is in one space and has to kill as many replicators as they can before dying (unlimited ammo).
If you didn't get the achievement upon finishing the game, first hit the save button on the end screen and then reload your page. If that didn't work, hit continue, and proceed to end the game again. That should do the trick :)
