Kinda like how Worms 3D screwed up.
no, it's much worse than that...
Worms 3D actually feels like the 2D Worms games
some parts of Metal Slug 3D feel like Metal Slug 1-5, like the weapons (but not even all of them, like the Rocket Launcher)...but most of the game is really bad...the tank just slows you down, it's easier to play WITHOUT the tank, since dodging projectiles is so easy (there's a cross showing where bullets are going to land)
I don't really like the new "hi-res" style of Metal Slug 6 either, why didn't they just keep the old style, which looked perfect and made the game famous for some of the best 2D graphics ever?
I'm looking forward to Metal Slug 6 anyway...maybe it'll be the last Metal Slug game, who knows?
Metal Slug 6 will be released for the PS2 soon, btw
