RS_Earthquake rc1

A coop/singleplayer survival map with dynamic difficulty, similar to Call of Duty zombies.

Install Instructions:

The download contains a README with full instructions, but here is the short version for singleplayer or LAN:

1. Add "+sv_allow_point_servercommand always" to your launch options, without the quotes.
2. Place the "_earthquake custom files.vpk" file into your custom folder.
3. Place the rs_earthquake_rs1.bsp file into your maps folder.
4. Start the map using your preferred method.

If you want to host a server or need more specific instructions read the README in the download zip.

Gamemode Description:

What does rs stand for?

Robot Survival

Robot Survival is a wave-based survival gamemode: every wave a certain number of melee bots are spawned, which you must kill in order to advance to the next wave. After which you gain money to buy weapons, upgrade those weapons, and open doors to explore the map. At the start the only weapons you can use are melee weapons and spy's revolver, but after a few waves you can buy the shotgun and each class’ weapons (once they are found in the map).

There is no real ‘victory’ in this mode, although there are only 100 rounds that can be fought through. So you could potentially fight through all 100 and win, but that would take a while.

The main goal of this gamemode is to shoot robots.
And if you would like to have a more relaxed time the map contains a cheat room, which allows you set up an endless wave with whatever difficulty you want.

Q: I only spawned with my melee! How do I get my weapons back?!

A: The shotgun can be purchased in the spawn room by using Uber canteens in the marked area. The other class’ weapons can be likewise purchased around the map.

Q: How do I open doors?

A: Each door has a counter which can be decreased by using Uber canteens in the marked area around that door. Once the counter reaches 0 the door will open.

Q: My game is lagging!

A: Here are a few things you can try:

1. Run a dedicated server.

By connecting to a dedicated server, the simulation workload can be spread out more evenly, even if you are running the server locally; which can improve your client’s performance (improving FPS). (Note: this will not be the case if your CPU is already working close to 100%).

2. Play with fewer people or lower the number of bot spawns in the cheat room. (the cheat room is located behind the double doors to the right of the spawn room upgrade station. After the first wave go in there hit the "-" button under number of bot spawns to lower the number of bots spawned per wave)

The map increases the number of bots spawned for every person (up to 6) which means that at 4+ people the game can lag.

3. Make sure you have adequate bandwidth.

This game mode requires a bit more bandwidth than normal, if your internet connection isn’t very strong and you are trying to play online; you may run into issues.

(Note: this doesn’t just mean your ping is bad, it means your download/upload bandwidth isn’t high enough to handle the traffic)

Q: Why can’t the engineer build anything?

A: The engineer needs to unlock his weapons just like every other class before he can build anything.

Q: Ok, I unlocked his weapons, now why can’t I build dispensers and teleporters?

A: Balance.

Engineer is easily one of the most powerful classes in this type of gamemode. The teleporter could allow you to easily move across the entire map preventing the bots from ever getting close to you. And the dispenser allows for turtling, by preventing the dispenser it forces players to go around the map for ammo, instead of just staying in one spot.

Q: Why can’t the medic revive or use his shield?

A: Balance and system limitations.

The shield messes up bots pathfinding; and if you have a few medics in a corner, you can hold off the bots infinitely without ever having to worry about getting hurt.

The removal of reviving is because of how player deaths are recorded internally, and allowing reviving would mess up the counter.

Q: Why is weapon X not allowed?

A: Some weapons (base jumper, quickfix, etc.) are removed because they would make the game too easy and you would be stupid not to use them.

Other weapons (Bison, eyelander, etc.) are removed because they don’t work properly with the HHH bots, upgrades, or some other part of the map (for example: because of how TF2’s upgrade system works, laser weapons can’t have their damage upgraded).

Lastly botkillers aren’t allowed because when there are removed the dangling bit isn’t removed and stays in front of your face for the rest of the game, which is annoying.

Q: What do you mean this map has “dynamic Difficulty”?

A: The number of bots spawned and the cost of items are directly proportional to the number of people playing the map. So theoretically the difficulty should be similar for 1 or 6 people, because each person will have to deal with the same number of robots and will have to spend the same amount of money to unlock items, regardless of how many people are playing.

Q: Wait, so does that mean that this map is singleplayer too?

A: Yes! That was one of my main goals when developing this map.

Maybe not FAQ but general mapping related questions

Q: What are the demo bots? Are they regular TF2 bots?

A: The bots are remodeled and reanimated, Horseless Headless Horsemen. Because of how TF2 handles standard bots you can only have about 21 of them at any one time (on blue in MVM). But there is no such limit on how many HHH you can have running around at once (the only limit you will run into is when your FPS drop to 5). When I tried doing this gamemode with standard bots I never felt like there were enough to feel like I was truly fighting a horde, and they often wouldn’t act how I wanted and would end up roaming the map instead of chasing the player.

Q: How did you do X?

A: I uploaded the vmf inside the Robot Survival Developer Kit here:

(for those people who want to know why I made this map)

When watching different shooter games I have seen that almost every one has had a zombie survival mode of some sort; and since I never got into any shooters besides TF2 I always wondered… how would our 9 favorite mercenaries fair in this situation? Well there has always been zombie fortress and other multiplayer mods, but it isn’t the same. You need a good internet connection (which I haven’t always been graced to have) and usually you must play as the zombies at some point (which isn’t as fun in my opinion). I wanted a purely coop/singleplayer zombie survival experience (like Call of Duty), but to my dismay there wasn’t one anywhere to be seen. So, I made one myself! 400 700 800 1000(?) hours after booting up hammer for the first time I am proud to release the first ever TF2 zombie survival map; and the best part is that it requires no server plugins of any type (at least for singleplayer or LAN play), just the map file and the custom VPK.

i love this map
subsequent versions are expected.

But the composition of the vpk is very bad. You might want to find a solution to using a robot rather than a HHH. or Keep the HHH, but spawn a specific robot is not bad.
Good map! I like the gamemode and its very fun to play with friends!
Its a very good map and I had fun playing it. It still needs lots of work like details and some bug fixes, but overall a good map to play.
