Pocket Tanks is a semi-freeware 2-tank Artillery Game. It's based on a game called Scorched Tanks (which itself was based on Scorched Earth). It features numerous weapons and expansion packs. Currently, with all expansions, the total number of weapons available is 250. Unlike the most tank artillery clones, the objective of this game is not to destroy the opponent. Instead, each player gets to choose 10 from the 20 randomly chosen weapons at the start of the game. The player who has more points when all weapons are fired, wins the game.
This game provides examples of:
Abnormal Ammo: Pretty much most of the arsenal. Did I mention tanks can shoot fleas?
Amazing Technicolor Battlefield: There are weapons that remove dirt, create dirt in various colors, color existing dirt, and apply thin layers of color to existing dirt; so 80% of the maps end up being this by the time the fight is over.
Blown Across the Room: Most weapons will move the target somewhat, but a select few will send their ass clear to the other side of the map. One weapon, Backfire, actually invokes this as a huge jump that unburies the user, but leaves them in a random spot.
Fixed Damage Attack: Several, including Sniper Rifle and Cannon Ball, which either do 100, or miss. Laser, Super Laser, and Phaser have the same effect, but wildly different other properties. Cheap Shot also does 20 damage, no questions asked.
Floating Platforms: Elevator, and Showdown invoke this. Also, several weapons negate the effects of gravity on dirt that they dislodge, creating these.
Flechette Storm: Many, MANY, of the weapons split into multiple projectiles at some point. Notable ones include: Streamers, which launches an incredible amount of bouncy projectiles for a short time; Lodestones, which launches homing flechettes; Burning Coals, whose projectiles burst into flame when near the enemy; and Nanobots, whose projectiles hover around the enemy, shooting lasers.
Burnt Popcorn. Does 10 damage on a direct hit, but if it's shot near an enemy in a crater the splitting sub-munitions and splashes of napalm can deal hundreds of points worth of damage. Similarly, Fireball, Popcorn, Fuzz Ball, Static Ball, and Buzzsaw can all deal more damage with multiple near misses than a direct hit.
Also, Solar Flare drops its projectiles over the entire map, dealing as much damage to the user as the target and thus being pretty pointless. However, if the user is buried under dirt or some other protection...
No Arc in Archery: Completely averted. Nearly every single weapon is launched in an arc. And the ones that don't, either come from above (Solar Flare, Glue Storm, Mass Driver), or are justified (Laser, Super Laser, X-Ray Cannon). And, well Cheap Shot.
Slap-on-the-Wrist Nuke: Mega Nuke and Mega Reaction are substantially weaker than their non-mega counterparts. The advantage is they have a larger area of effect.
Trippy Finale Syndrome: There are weapons that remove dirt, create dirt in various colors, color existing dirt, and apply thin layers of color to existing dirt; so 80% of the maps end up being this by the time the fight is over. Add in that weapons exist that create floating platforms, and while dirt that has nothing beneath it will fall, certain weapons let dirt hover. By the end of the fight, chances are you're either on a flat, empty nothing, or a crazy, multicolored Platform Hell.
