Trenched is actually very good. The matchmaking works really well, which is a good thing because it's a lot more fun to play with other people than it is to play by yourself. It's still fun to play alone, but it can get really stressful once you complete the first region. The amount of customization is pretty damn impressive for an Arcade game, and half the fun is outfitting your mech (or trench) with the different weapons and body types available. It's a definite balancing act. You need to make sure that you are outfitted with weapons strong enough to damage whatever type of enemy is going to prevalent on each particular battlefield, but you also want to make sure that you are carrying guns that reload fast enough, carry enough ammunition for the situation, and make enough scrap when shooting enemies to build up your turret placements as needed.

I wonder when they're going to release it in Europe.

Some guy already has the name Trench and variations there of copyrighted for some board game, hence the delay.
