Demonator1 here (a.k.a. the creator of this game) with some helpful little tips. One is that you should use cover when you can. Don't run up and fire. Kill all enemies and take your time before reaching the castle. Use cannons to destroy hard to reach turrets. There is invisibility and invincebility hidden in a radom bunker. This game is for experienced and the experts. No begginers should attmept. Thank you for your time and enjoy the game.
