More info about th Big Update upcoming for the Dota Underlords has been revealed again. This time, Valve share a very interesting feature coming for the gameplay mechanism. Along with another selection of heroes drawn from the Dota 2 roster, the game will be adding a system to keep the hero pool from overflowing. Specifically, it'll be throwing some of them in jail.

Here's how (and why) it works. As the hero pool expands, it becomes harder and harder to rank up the heroes you've purchased from the shop, since the odds of finding matches for heroes on your bench get reduced each time a new hero is added to the general pool. Valve says it doesn't plan on removing any of the heroes that have appeared in the beta season, and so when season one kicks in and adds 12 new heroes to the pool, some of them will get tossed in jail for 24 hours.

Each day, a different group of 8-12 heroes will be jailed, effectively banning them from appearing in the shop. This won't be completely random: Valve says that the list of jailed heroes for each day will be created such that players can still complete every alliance.

A nice added benefit of this system is that it prevents an established meta from taking hold and making the game feel stale. You're going to be faced with different composition options each day.

Apart from the new feature, Dota Underlords will add two new mode: Duos and Freestyle Mode.

In Duos mode, Vavle said you can find a partner, party up and battle against 7 other gangs.

As for the Freestyle Mode, in this mode you have full control of the board, and can create any scenario you can think of. Use it to explore army compositions, or test new hypotheses. You can then share your design with friends and the community.

At last, more news about the Update will come tomorrow..Stay tuned.
