Enemy orcs are coming from every angle to try to destroy the Infinite Power Generator! Luckily for you, each orc is carrying a big gem that can be sold for gold. As the conductor, your job is to spend gold on buying new train carriages to help defend the generator - flamethrowers, snipers, cannons, railguns, and dozens more can be purchased and added to the train to help with defense. Buy 3 of the same type of carriage to upgrade it to the next level. For example, buying 3 level 1 Snipers will merge into a level 2 Sniper, and 3 level 2 snipers will merge into a level 3 Sniper. You can upgrade like this infinitely! Be careful - bosses will spawn every 5 minutes to try to take the generator out! At 5 minutes, 15 minutes, and every 15 minutes after, bosses will drop a Relic Chest, which can be opened for power-ups that last for the rest of the game. Enemy orcs might also drop tickets. Use tickets in the "Boons" menu to unlock additional permanent upgrades! How long can you last against the orc hordes?
