I bought and loved this game. Its challenging to keep me interested and often hard so that i can't pass a stage in 1 try (maybe i shouldn't play it on hard) The RnD aspect of the game is great. I love stealing severed limbs from the enemy and rushing them, back to base so I can make weapon or part. A bit of strategy, if your combot loses a limb, you can click on the bot then any limb on the ground, it will attatch to your bot. Try it with a flying bot for fun. In Multi player games, build combots with 2 arm types that your ally does not posess, then run that bot over to your ally and pop its arms off in his camp, have your all do the same and you can get a leg up on the computer, or other human players. To pop off an arm from your bot, select bot then left click on the arm.
