CashGrabbers is a multiplayer 3D CTF like (Capture the Flag inspired) game where the objective of the game is to grab as much money for your team as possible. The game allows up to 4 teams of 4 people each.
At the start of the game each team starts on opposite sides of a game map (there are a select amount of maps) and their spawn area has 1-3 safes that corresponds to each team's money count. The maps will vary from mazes to open spaces and money (in the form of gold bars) will spawn throughout the maps. The only objective of the game is to get as much gold for your team as you can and return them to your team's safes before the round time runs out. There are also secondary objectives that you can capture for your team which will generate a small amount of gold for your team per minute. Each player has a knife and a few traps that can be used to stop and kill other players and grab the gold bars that they were carrying. Random events like natural disasters and UFO abductions will also occur during the game which will also kill the player and drop their gold bars, allowing for allies to rescue the gold or for enemies to wait and pounce on the opportunity.
The safes themselves can also be opened up and gold can be stolen from open safes, so having an attack team and a defense team is essential to victory! It takes time for players to open the safes and therefore vulnerable to being stabbed in the back by the enemy, but once the safes are open you can steal and acquire gold bars at a faster rate than running around the map and picking them up. Safes can be closed again by allies players so that enemies have to spend more time to reopen the safes if they wish to steal gold from the opposing team's safes.
Each base also has a shop where player's can spend their gold to get more weapons/gadgets and other useful items that will help in getting more gold bars, whether the items will help the player move around the map faster, steal from safes faster, or killing enemies from a range to secure their gold bars.
Imagine the picture below, but with gold bars scattered around the middle, and safes/shop inside the red/blue bases.
