Back2Back is an arcade strategy game, which delivers a full range of action experience, fusing a classic defense gameplay with action based tactics. Lead a squad of space marines through many unique levels and survive the massive attacks of bloodthirsty robot hordes to escape the hell of abandoned planet.
You can move units not only by clicking the desired square but just the leading path. Replay feature is a great way to farm orbs and get upgrades then. Different unit types are great against different enemies.
Flamerat does x2 damage against fast moving targets. Stinger does x3 damage against flyers. Sniper is great against healers. Mortar is great against huge robots.
