Fun but…

The chaos people bring from around the world make it a great game. However the game tries to sell you everything when it should a challenge to get and if you lose you can buy it. This pay to win is what eventually makes the game collapse. Honestly if it was hardcore vs casual with money then this can become so big

Devs are greedy and don’t care

Devs are the greediest people I have even seen, you have to spend spend spend to even have a chance and I’m not talking a small amount, enough to buy a house. They just don’t care and encourage pay to win and bullying. They also name their bots very offensive names and do not care.

Prepare to spend some money.

I played this game for over four years. What started out as a fun game has turned into a money pit. If you want to get anywhere in this game, expect to spend money every day. The new level 11 soldiers have become my children, and they are just as expensive. Keep them alive because healing them is just as expensive as making them.

The game is amazing so far

Addicted

Last Fortress: Underground is one of those games that grabs you and it rarely disappoints. While obviously tilted to the player who pays you can play for hours and still want more…9 out of 10.
