+
+**Important**: While the code and some art are on Apache 2.0 license, other art is not (i.e. some art cannot be redistributed with e.g. forks of this project without acquiring a license; good news is that you'll be supporting indie game artists on itch.io if you do choose to do that). See LICENSE file in game subdirectories for details.
+
+**Disclaimer**: This isn't an official product. It's a highly experimental CTF-like idea implemented by a couple of engineers in a couple of proverbial evenings. Expect errors, bugs, and problems.
+
+This directory contains all 6 versions of the competition platform (speed-hacking game) used at Google CTF 2020 Final Event aka Hackceler8, including the "pre-tournament" version shared with the competing teams a week before the tournament.
+
+See [Google CTF Hackceler8 website](https://capturetheflag.withgoogle.com/hackceler8) for more details.
+
+To play the game you'll need docker and docker-compose (can be on a Linux VM), and a browser (tested mostly on Chrome). Just enter any `match-*` subdirectory and type:
+
+`docker-compose up --build`
+
+After the game is running, connect with the browser to `http://127.0.0.1:4567/` (or whatever IP the Linux VM you are using might have) and use **player**/**asdf** as credentials.
+
+**Important**:  This setup is usable for testing only. Don't use this to run
+competitions! Check out [KCTF](https://github.com/google/kctf) instead.
+
+During the tournament setting players had access to the source code of both the client and the server side of the game, but did not have access to source code of the challenges (nor obviously to the flags). Any client-side game glitching / hacks / mods / http proxies / etc were allowed (and actually required to complete some challenges) - do note that there is an anti-cheat which will block some obvious stuff.
+
+If you're wondering how does the game work - well, that's something the players had to figure out during the competition as well, so... good luck! :)
+
+Hint: Use [Tiled](https://www.mapeditor.org/) for viewing the map.
+
+## Known issues
+
+* See README.md file in `match-*` subdirectories.
+* Server-side saving of game state is disabled - if you want to re-enable it, check `game_service.js` and look for `/tmp/state_` - there's a comment there explaining what to do. Afterwards you can run the game (`main.js`) with the state file as an argument to recover the state.

+To run the game just use `docker-compose up` and connect to port :4567 with a
+web browser.
+
+Default username is `player` and default password is `asdf`.

+**NOTE**: This setup is usable for testing only. Don't use this to run
+competitions! Check out [KCTF](https://github.com/google/kctf) instead.

+
+### Known issues
+
+Honestly there are many known issues as this was a purely experimental project
+coded in a very limited time by just two people. But here are some major ones
+anyway:
+
+* If the browser's game tab becomes inactive, the game will not send any packets
+to the local game server, but will try to send all packets it was supposed to
+send the moment it becomes active. This actually might OOM the tab.
+**WORKAROUND**: Just refresh the tab, no effective state is lost.
+* In match 1 there are only 7 tasks, not 8 as the UI indicates.

+
+      "Derivative Works" shall mean any work, whether in Source or Object
+      form, that is based on (or derived from) the Work and for which the
+      editorial revisions, annotations, elaborations, or other modifications
+      represent, as a whole, an original work of authorship. For the purposes
+      of this License, Derivative Works shall not include works that remain

+      this License, each Contributor hereby grants to You a perpetual,
+      worldwide, non-exclusive, no-charge, royalty-free, irrevocable
+      copyright license to reproduce, prepare Derivative Works of,
+      publicly display, publicly perform, sublicense, and distribute the

+

+      by such Contributor that are necessarily infringed by their
+      Contribution(s) alone or by combination of their Contribution(s)
+      with the Work to which such Contribution(s) was submitted. If You
+      institute patent litigation against any entity (including a
+      cross-claim or counterclaim in a lawsuit) alleging that the Work
+      or a Contribution incorporated within the Work constitutes direct
+      or contributory patent infringement, then any patent licenses
+      granted to You under this License for that Work shall terminate
+      as of the date such litigation is filed.
+
+   4. Redistribution. You may reproduce and distribute copies of the
+      Work or Derivative Works thereof in any medium, with or without
+      modifications, and in Source or Object form, provided that You
+      meet the following conditions:
+
+      (a) You must give any other recipients of the Work or
+          Derivative Works a copy of this License; and
+
+      (b) You must cause any modified files to carry prominent notices
+          stating that You changed the files; and
+
+      (c) You must retain, in the Source form of any Derivative Works
+          that You distribute, all copyright, patent, trademark, and
+          attribution notices from the Source form of the Work,
+          excluding those notices that do not pertain to any part of
+          the Derivative Works; and
+
+      (d) If the Work includes a "NOTICE" text file as part of its
+          distribution, then any Derivative Works that You distribute must
+          include a readable copy of the attribution notices contained
+          within such NOTICE file, excluding those notices that do not
+          pertain to any part of the Derivative Works, in at least one
+          of the following places: within a NOTICE text file distributed
+          as part of the Derivative Works; within the Source form or
+          documentation, if provided along with the Derivative Works; or,
+          within a display generated by the Derivative Works, if and
+          wherever such third-party notices normally appear. The contents
+          of the NOTICE file are for informational purposes only and
+          do not modify the License. You may add Your own attribution
+          notices within Derivative Works that You distribute, alongside
+          or as an addendum to the NOTICE text from the Work, provided
+          that such additional attribution notices cannot be construed
+          as modifying the License.
+
+      You may add Your own copyright statement to Your modifications and
+      may provide additional or different license terms and conditions
+      for use, reproduction, or distribution of Your modifications, or
+      for any such Derivative Works as a whole, provided Your use,
+      reproduction, and distribution of the Work otherwise complies with
+      the conditions stated in this License.
+
+   5. Submission of Contributions. Unless You explicitly state otherwise,
+      any Contribution intentionally submitted for inclusion in the Work
+      by You to the Licensor shall be under the terms and conditions of
+      this License, without any additional terms or conditions.
+      Notwithstanding the above, nothing herein shall supersede or modify
+      the terms of any separate license agreement you may have executed
+      with Licensor regarding such Contributions.
+
+   6. Trademarks. This License does not grant permission to use the trade
+      names, trademarks, service marks, or product names of the Licensor,
+      except as required for reasonable and customary use in describing the
+      origin of the Work and reproducing the content of the NOTICE file.
+
+   7. Disclaimer of Warranty. Unless required by applicable law or
+      agreed to in writing, Licensor provides the Work (and each
+      Contributor provides its Contributions) on an "AS IS" BASIS,
+      WITHOUT WARRANTIES OR CONDITIONS OF ANY KIND, either express or
+      implied, including, without limitation, any warranties or conditions
+      of TITLE, NON-INFRINGEMENT, MERCHANTABILITY, or FITNESS FOR A
+      PARTICULAR PURPOSE. You are solely responsible for determining the
+      appropriateness of using or redistributing the Work and assume any
+      risks associated with Your exercise of permissions under this License.
+
+   8. Limitation of Liability. In no event and under no legal theory,
+      whether in tort (including negligence), contract, or otherwise,
+      unless required by applicable law (such as deliberate and grossly
+      negligent acts) or agreed to in writing, shall any Contributor be
+      liable to You for damages, including any direct, indirect, special,
+      incidental, or consequential damages of any character arising as a
+      result of this License or out of the use or inability to use the
+      Work (including but not limited to damages for loss of goodwill,
+      work stoppage, computer failure or malfunction, or any and all
+      other commercial damages or losses), even if such Contributor
+      has been advised of the possibility of such damages.
+
+   9. Accepting Warranty or Additional Liability. While redistributing
+      the Work or Derivative Works thereof, You may choose to offer,
+      and charge a fee for, acceptance of support, warranty, indemnity,
+      or other liability obligations and/or rights consistent with this
+      License. However, in accepting such obligations, You may act only
+      on Your own behalf and on Your sole responsibility, not on behalf
+      of any other Contributor, and only if You agree to indemnify,
+      defend, and hold each Contributor harmless for any liability
+      incurred by, or claims asserted against, such Contributor by reason
+      of your accepting any such warranty or additional liability.
