There was a lot of excitement when Eutechnyx announced it was developing a new Warhammer 40k game late last year. The Warhammer fan base might not be very deep, but it's fanatically devoted. With that in mind, the response to this trailer is understandably negative. It looks less like the combat strategy games usually associated with Warhammer, and more like Plants vs. Zombies.
In Warhammer 40K: Storm of Vengeance, players try to take over lanes by placing structures and units on them. The units march across the screen, shooting at everything in their path. However, the enemy is doing the same thing. You can upgrade your units and deploy special abilities to get an advantage, though. This doesn't necessarily look like a bad game, but it's very different than most people were expecting.
Warhammer 40K: Storm of Vengeance is set to hit beta testing on February 27th and launch a month later. The price is quoted as £2.99 on Android, so maybe $3.99-4.99. Happily, the developers say there won't be any in-app purchases.
