Using wpe pro I got about 3 million rp in about 10 minutes and a couple thousand tech points for my tier. Before I begin, all credits go to PhySixs and his youtube channel. You should check out his videos for a tutorial on how to level up very quickly; I'm just spreading the word for this exploit.
1. Before you start, go to view>option in wpe and make sure that send is the only checked box.
2. To begin, open robocraft and wpe and find a game in robocraft. Once you are in the game, switch to wpe and start "recording" packets with the "start logging" button.
3. Play the round like usual and get at least one kill. If you do not get a kill, you will have to try again. (you should stop recording packets until you find a new match to prevent clutter)
4. When you finish the game with a kill, wait until your ship repairs, then stop the wpe recording and you should see many packets pop up in blue text and what-not inside wpe.
5. Sift through these and try to find "awardkillchain". It will be listed under "send" on the right in blue text. Once you find the packet, right click it and then click send.
6. A new window will pop up, and here you need to change the timer to 100 milliseconds and set wpe to send the packet 500 times. (the box directly above timer). Once it sends 500, wpe will automatically stop sending packets.
7. Now, you need to find another game in Robocraft. Once you load into the game, immediately exit to the main menu without doing shit.
The report should list about 500 kills if done correctly. If you want a larger reward, send the packet continuously while you watch a youtube video or something. I hit about 9000 in continuous and that's how I got my 3 million.
Sorry if the directions are unclear
Some common issues:
Wpe does not detect Robocraft/does not detect sent packets - Run both wpe and robocraft as admin. Also do not use steam version
Sometimes sending too many packets continuously will cause an error. Stick to 500 to be safe if this happens.
If you are confused, check out PhySixs youtube channel. He made a video tutorial on this.
