Ok so the title may be confusing but hear us out, so GeForce removed the feature of using Garrys mod on there mobile version of there site so this is a better alternative to playing.
Colored usernames using unity rich text like <color=blue>imblue</color> it makes user names more cool also please increase the limit for characters and symbols for names of player and server.
Can you make new npc s like an Alien, Bigfoot, even trollge.
So we bought a flamethrower and we noticed every time we threw a flame on a item our game just crashes and sometimes if we stay on the game for a long time, it crashes can you guys just fix the bug of crashing already like really.
Bro bring back the old game you couldve just ruined the game even more you models just like Garrys mod back then and then this is not it this is just different like oh our God like please fix this bro like please this game was our dream game but instead you changed it its nothing like use bad back then back then was very fun fix it.
Umod is so fun and players are killing us.
Add 120fps support for iPhone 13 Pro and pro max also we cant see the fps meter because of the vessels on our phone.
Spas 12, fn scar, awm, crowbar, mp5k, Pkm, Glock 18 ,revolver, berreta, ar 15, m1911, and combat shotgun. And can you make the gun bar look like g mods and can you make the cars blow up when they are destroyed. And here is the last smg we want you to add. Krissvictor and add a knife plz and add a half magazine reload and a new empty magazine reload plz all of this stuff should make your game better then how it is now because people just stoped playing and we love your game and can you add a Addon maker so people can make stuff and next bots and plz add a running system for the game and when you run and jump you go faast.
We Like the RPGS They are really cool but In want a couple NUKES Like fat man and little boy Anyway THIS GAME IS REALLY COOL its a really cool game but we will give it five stars if you add nukes.
The loading screen took so long to load it felt like an hour to load this game.
None of our worlds can save on to our umod game im playing on iphone 12.
Its a ok game if youre looking for something similar to gmod but cant get it on steam or your looking for a game similar to gmod for your phone or tablet other than that its a pretty ok game.
The loading screen keeps freezing and wont continue we keep closing the app and getting back on the app and it keeps freezing.
The game literally never loads on iphone it says connecting to server but it never does.
It just stops loading fix your game and more people will give u a 5 star review.
It wouldnt let us do anything.
It literally lagged out our entire phone.
When we enter the fame it wont even load.
Its Garrys mod for iPad try it.
There is one problem tho,get rid of the Christmas hats its September.
Very fun game but our maps dont save and dont show up to load.
Ok so when we try to save a map that we worked hard on it says it was successful but when we go to make server it doesnt even work. The saves arent even in there so yeah we wasted time on this so 3/5 , plz fix this bug soon and we will rate this a 5.
So, rewind back to 2019, This game whats EXPLODING with players, bugs, etc. And, thats what made it fun. But now Last time we played, there was a lack of servers and players, lost ALL the saved maps we spent HOURS on. Wouldnt recommend this for people who like it at first glance.
Im Sorry we Ruined Your Game Its Just we Think Its Fun To Make Everyone we Meet In A Game Triggered And This Game Was Just A Another Victim About Like 8 Months After we Started Playing Everyone Was Gone Only Like One Guy On The European Server So Im Really Sorry Please Forgive we Will Do Anything To Amend our Mistakes.
Some glitches made the game fun idc if its realistic or not like the glitch where there was a hole to the void in a map or choose whatever prob and fly on it with the gravity gun or just pick a glitch that could quickly make you go to the air like idc if its not realistic or not and the fact almost everyone like the glitches and used them its sad that barely any survived but Im glad some of them died of.
We would like to play more maps it doesnt matter what kind we would just like some more maps please and thank you.
It makes us give it our Debit card information and just doesnt want us to play after we give them it.
We used to like this game until the update, every time we save a world it says save success then we go to load map and there is nothing at all.
Im waiting for it and we are bored but we used to have it and it was really fun so Im now getting it back after we deleted it when we deleted it it was a long time as well why is it taking so long.
We tried to get in but our game didnt load in and it was stuck saying connecting to the sever for like an hour.
In the middle of loading it stops.
Problem loading into the game after the 2.6.0 update.
We dont know why but when we launch the game it says connecting into server even though it halfway and stays like that.
Ever since 2.6.0, the first loading screen stops at halfway, please fix this problem.
The game didnt so we cant really say much about it if we couldnt play it.
When we play it we cant even play it it says connecting to server but it isnt so we dont even know what the game is like plz fix:(.
Half way through the loading screen ot just stops.
We literally waited 30 minutes and it didnt even load we have Internet in the Internet works but it doesnt load it takes forever we wouldnt say dont download it but please fix this issue its not the Internet we waited so long for this update and we cant even play it so we give it a one star.
Our game wont work it wont let us join pls fix that.
This game hasnt loaded what do ever we have it at least ten minutes and it didnt even make progress, dont download, bad game.
We think we made the mod? Well we think and The mod is Trollge.
We dont know why but when we updated our phone the game stopped working we even deleted it and re downloaded the game but still did not work pls fix.
It is good but there is a glitch where it crashes the game which is really annoying. We cant ever finish a project because this glitch crashes our game all the time. We always get mad because our project is usually like 75 percent done or less. If this glitch wasnt a thing we would have gave a 5 star review.
Im trying to make something in a Map but the server keeps crashing.
Its a fun game at first then its just boring after you play it for a while and has tons of gore.
The game is good, but we want singleplayer to be offline.
You need to add a truck a semi and a trailer.
We want real bosses more levels more items and more cheap characters.
We need you to add more props for the ultimate mall named it after the ultimate sandbox but more to Continue if you can play the game.
