I bought Booster Trooper at launch since it seemed like it could be a fun game. At the time, there were not many platform shooters, Apparently, I was not the only one thinking it could be a good game, because quite some people bought the game. I can tell since my rare achievements list only contains Booster Trooper achievements and I'm quite sure it will take a long time (forever) to get different achievements from other games.
Why, you say? Simply, because apparently most of the players did get a few achievements, but never returned to the game. I used to love the rare achievements on my profile page but obviously, it's not that fun for me anymore.
Booster Trooper is an online platform shooter. Sadly, there's no one playing the game anymore so you've got the option to play vs bots.
Gameplay is all pretty basic but instead of jumping you use a jetpack to get higher up the platforms. There are multiple weapons like; minigun, sniper rifle, pistol.... you get the picture. There are some special weapons and powerups to pick up.
Graphically, the game looks pretty awful, even at launch. It did not bother me much personally but it simply does not look good.
Overall Booster Trooper is an OK game, which can only be recommend buying it together with some buddies, weren't it for the fact the price tag of the game is 5 bucks (4 pack: 15,-) which is way too much. Also, there are better games of the same genre like The Showdown Effect.
