A new version was released tonight, the biggest change being Contracts. Users can take out a contract at a specific location. They can get to that location by clicking on a map, or by entering a address/location name.
Once a contract has been taken out, anyone that places a bomb near the contract point will get a bonus.
Some back-end work needs to be done with this (news, points for who placed it when the contract is fulfilled, etc). Contracts have always been in the base system, just not directly available on the Android app - "Missions" are just contracts that are auto-gen'd.
App install count has gone to around 7,800. 10k just around the corner!
